Eia ke kikowaena nūhou o ka ʻoihana hoʻoheheʻe injection o Baiyear.Ma hope aʻe, e puʻunaue ʻo Baiyear i ke kaʻina hana hoʻoheheʻe i loko o kekahi mau ʻatikala e hoʻolauna i ka nānā ʻana i nā mea maka o ke kaʻina hana hoʻoheheʻe ʻia, no ka mea he nui loa nā ʻike.A laila ka ʻatikala ʻekolu.

(5).BS (K material)
1. Hana o BS
ʻO BS kahi copolymer butadiene-styrene, nona kekahi ʻano paʻakikī a me ka elasticity, haʻahaʻa paʻakikī (ʻoi aku ka palupalu) a me ka ʻike maikaʻi.ʻO ka umekaumaha kikoʻī o ka mea BS he 1.01f\cm3 (e like me ka wai).He maʻalahi ka waihoʻoluʻu o ka mea, maikaʻi ka wai, a maʻalahi hoʻi e hana a hana.
2. ʻO ke kaʻina hana o BS
He 190-225 °C ka lō'ihi o ka ho'oponopono 'ana o BS, a 'o ka mahana o ka mold he 30-50 °C.Pono e maloʻo ka mea ma mua o ka hana ʻana, no ka maikaʻi o ka wai, hiki ke haʻahaʻa ke kaomi injection a me ka wikiwiki.

(6).PMMA (Acrylic)
1. Hana o PMMA
ʻO ka PMMA kahi polymer amorphous, i kapa ʻia ʻo plexiglass.ʻO ka māliko maikaʻi, ke kūpaʻa wela maikaʻi (ka wela deformation wela o 98 ° C), a me ke kūpaʻa hopena maikaʻi.Loaʻa i kāna mau huahana ka ikaika mechanical medium, haʻahaʻa ka ʻili o ka ʻili, a maʻalahi ke ʻoki ʻia e nā mea paʻakikī a waiho i nā meheu, e like me PS.ʻAʻole maʻalahi ka maʻi a me ka māwae, a ʻo ka umekaumaha kikoʻī he 1.18g/cm3.
Loaʻa i ka PMMA nā waiwai optical maikaʻi loa a me nā waiwai kūʻē i ka wā.ʻO ke komo ʻana o ke kukui keʻokeʻo e like me 92%.He haʻahaʻa loa ka birefringence o nā huahana PMMA a kūpono loa no ka hana ʻana i nā disc wikiō.Loaʻa i ka PMMA nā waiwai kolo wela.Hiki i ka pohā koʻikoʻi ke hoʻonui i ka ukana a me ka manawa.
2. Kaʻina hana o PMMA
He koʻikoʻi nā koi o ka hoʻoponopono ʻana i ka PMMA, a paʻakikī loa ia i ka makū a me ka mahana.Pono e hoʻomaloʻo piha ʻia ma mua o ka hana ʻana (ʻo 90 ° C nā kūlana maloʻo i manaʻo ʻia, 2 ~ 4 mau hola).°C) a me ka hoʻoheheʻe ʻana ma lalo o ke kaomi, ʻoi aku ka maikaʻi o ka mahana o ka mold 65-80 °C.
ʻAʻole maikaʻi loa ka paʻa ʻana o ka PMMA, a e hoʻohaʻahaʻa ʻia ia e ka wela kiʻekiʻe a i ʻole ka noho lōʻihi ʻana i ka mahana kiʻekiʻe.ʻAʻole pono ka nui o ka wikiwiki (e pili ana i 60%), a ʻo nā ʻāpana PMMA mānoanoa e pili ana i nā "voids", pono e hana ʻia me ka hoʻohana ʻana i kahi puka nui, "haʻahaʻa haʻahaʻa haʻahaʻa, kiʻekiʻe kiʻekiʻe ka wela, lohi wikiwiki" injection. ʻano hana.
3.Typical application range: automotive industry (signal equipment, instrument panels, etc.), pharmaceutical pharmaceutical (koko waihona ipu, etc.), Industrial applications (video discs, light diffusers), consumer goods (inu kīʻaha, stationery, etc. ).

(7) PE (polyethylene)
1. Ka hana a PE
ʻO PE ka plastic me ka puka nui loa ma waena o nā plastics.Hōʻike ʻia ia e ka maikaʻi palupalu, non-toxic, kumu kūʻai haʻahaʻa, ka hana maʻalahi, kūpaʻa kemika maikaʻi, ʻaʻole maʻalahi i ka corrode, a paʻakikī ke paʻi.ʻO ka PE he polymer crystalline maʻamau.
He nui nā ʻano, hoʻohana mau ʻia ʻo LDPE (low density polyethylene) a me HDPE (high density polyethylene), ʻo ia nā plastic translucent me ka ikaika haʻahaʻa a me ka gravity kikoʻī o 0.94g/cm3 (ʻoi aku ka liʻiliʻi ma mua o ka wai);haʻahaʻa haʻahaʻa haʻahaʻa LLDPE resins (ʻO ka haʻahaʻa haʻahaʻa ma mua o 0.910g / cc, a ʻo ka nui o LLDPE a me LDPE ma waena o 0.91-0.925).
ʻOi aku ka palupalu o ka LDPE, (ʻike mau ʻia ʻo ka pulupulu palupalu) ʻike pinepine ʻia ʻo HDPE he ʻōpala palupalu paʻakikī.ʻOi aku ka paʻakikī ma mua o LDPE a he mea semi-crystalline.Hiki mai ke koʻikoʻi o ke kaiapuni.Hiki ke hōʻemi ʻia ke koʻikoʻi o loko ma o ka hoʻohana ʻana i nā mea me nā ʻano kahe haʻahaʻa loa, a laila e hōʻemi ana i ke ʻano haki.He mea maʻalahi ke hoʻoheheʻe i loko o nā mea hoʻoheheʻe hydrocarbon ke kiʻekiʻe ka mahana ma mua o 60 ° C, akā ʻoi aku ka maikaʻi o kona kūpaʻa ʻana ma mua o ka LDPE.
ʻO ka crystallinity kiʻekiʻe o HDPE ka hopena i kona kiʻekiʻe kiʻekiʻe, ikaika tensile, kiʻekiʻe wela distortion wela, viscosity a me ka paʻa kemika.ʻOi aku ka ikaika o ka pale ʻana ma mua o LDPE.He haʻahaʻa ka ikaika hopena o ka PE-HD.Hoʻomalu nui ʻia nā waiwai e ka puʻupuʻu kaumaha a me ka molecular weight distribution.
ʻO ka HDPE kūpono no ka hoʻoheheʻe ʻia ʻana he haiki haiki ke kaumaha.No ka mānoanoa o 0.91 ~ 0.925g / cm3, kapa mākou iā ia ke ʻano mua o PE-HD;no ka nui o 0.926 ~ 0.94g / cm3, ua kapa ʻia ʻo ia ka lua o ka HDPE;no ka nui o 0.94 ~ 0.965g / cm3, ua kapa ʻia ʻo ia ka lua o ka HDPE ʻO ke kolu o ka HDPE ʻano.
He maikaʻi loa nā hiʻohiʻona kahe o kēia mea, me ka MFR ma waena o 0.1 a me 28. ʻO ke kiʻekiʻe o ke kaumaha mole, ʻoi aku ka maikaʻi o nā ʻano kahe o LDPE, akā ʻoi aku ka maikaʻi o ka ikaika o ka hopena.Hiki i ka HDPE ke pohā i ke koʻikoʻi o ke kaiapuni.Hiki ke hoʻemi ʻia ka māhā ʻana me ka hoʻohana ʻana i nā mea me nā waiwai kahe haʻahaʻa loa e hōʻemi i ke kaumaha o loko.Hoʻoheheʻe maʻalahi ka HDPE i loko o nā mea hoʻoheheʻe hydrocarbon ke kiʻekiʻe ka mahana ma mua o 60C, akā ʻoi aku ka maikaʻi o kona kūpaʻa ʻana i ka hoʻoheheʻe ʻana ma mua o ka LDPE.
 
ʻO ka LDPE kahi mea semi-crystalline me ka hoʻohaʻahaʻa kiʻekiʻe ma hope o ka hana ʻana, ma waena o 1.5% a me 4%.
ʻO ka LLDPE (Linear Low Density Polyethylene) he kiʻekiʻe o ka tensile, ke komo ʻana, ka hopena a me ka waimaka i mea e kūpono ai ka LLDPE no nā kiʻiʻoniʻoni.ʻO kona kūpaʻa maikaʻi ʻana i ke koʻikoʻi koʻikoʻi o ke kaiapuni, ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka pale kaua ʻana i ka LLDPE e nani ai no ka paipu, ka extrusion pepa a me nā noi hana a pau.ʻO ka noi hou loa o LLDPE he mulch no nā pae ʻāina a me nā linings no nā loko ʻōpala.
2. Kaʻina hana o PE
ʻO ka hiʻohiʻona kaulana loa o nā ʻāpana PE ʻo ia ka nui o ka hoʻoheheʻe ʻana o ka molding, hiki ke hoʻohaʻahaʻa a me ka deformation.He haʻahaʻa ka wai o ka mea PE, no laila ʻaʻole pono e maloʻo.Loaʻa i ka PE kahi ākea ākea kaʻina hana a ʻaʻole maʻalahi ka decompose (ʻo 320 ° C ka mahana decomposition).Inā nui ke kaomi, e kiʻekiʻe ka mānoanoa o ka ʻāpana a e liʻiliʻi ka liʻiliʻi.
ʻO ka liʻiliʻi o ka PE he medium, pono e hoʻomalu pono ʻia nā kūlana hana, a e mālama mau ʻia ka mahana o ka mold (40-60 ℃).ʻO ka degere o ka crystallization o PE pili i nā kūlana kaʻina hana.He kiʻekiʻe ka mahana maloʻo a me ka wela haʻahaʻa haʻahaʻa, a ʻoi aku ka haʻahaʻa o ka crystallinity.I ka wā o ka crystallization kaʻina hana, ma muli o ka anisotropy o ka shrinkage, ke koʻikoʻi o loko ke koʻikoʻi, a ʻo nā ʻāpana PE e maʻalahi i ka deformation a me ka haki.
Hoʻokomoʻia ka huahana i loko o ka waiʻauʻau i loko o ka wai wela ma 80 ° C, hiki ke hoʻomaha i ke kaomi i kekahiʻano.I ka wā o ke kaʻina hana, ʻoi aku ka kiʻekiʻe o ka mahana a me ka mahana o ka mold, a ʻoi aku ka haʻahaʻa o ke kaomi injection ma lalo o ke kumu o ka hōʻoia ʻana i ka maikaʻi o nā ʻāpana.ʻO ka hoʻoluʻu ʻana o ka ʻōpala e koi nui ʻia e wikiwiki a ʻaʻahu, a e wela ka huahana i ka wā demoulding.
Hoʻomaloʻo HDPE: ʻaʻole koi ʻia ka maloʻo inā mālama pono ʻia.Ka wela hehee 220~260C.No nā mea me nā molekala nui, ʻo ka pae wela hoʻoheheʻe i ʻōlelo ʻia ma waena o 200 a 250C.
ʻO ka mahana wela: 50 ~ 95C.Pono nā ʻāpana plastik me ka mānoanoa o ka pā ma lalo o 6mm e hoʻohana i ka mahana o ka poni kiʻekiʻe, a ʻo nā ʻāpana plastik me ka mānoanoa o ka paia ma luna o 6mm pono e hoʻohana i ka wela haʻahaʻa.Pono ke ʻano o ka mahana hoʻoluʻu o ka ʻāpana plastik e hōʻemi i ka ʻokoʻa o ka emi ʻana.No ka manawa pōʻaiapili machining maikaʻi loa, ʻaʻole i emi iho ke anawaena o ke kahawai hoʻoluʻu ma lalo o 8mm a ʻo ka mamao mai ka ʻili o ka mold ma loko o 1.3d (kahi "d" ke anawaena o ke kahawai hoʻomaha).
ʻO ke kaomi ʻana: 700 ~ 1050bar.ʻO ka wikiwiki o ka injection: Paipai ʻia ke kiʻekiʻe kiʻekiʻe.Nā mea holo a me nā ʻīpuka: Aia ke anawaena o ka mea kukini ma waena o 4 a me 7.5mm, a ʻo ka lōʻihi o ke kukini e like me ka pōkole.Hiki ke hoʻohana ʻia nā ʻano ʻīpuka like ʻole, a ʻaʻole pono ka lōʻihi o ka puka ma mua o 0.75mm.He kūpono kūpono no ka hoʻohana ʻana i nā mold runner wela.
ʻO ka waiwai "soft-on-stretch" o LLDPE he mea pōʻino i ke kaʻina hana kiʻiʻoniʻoni puhi, a ʻaʻole paʻa ka pahu kiʻi ʻoniʻoni o LLDPE e like me ka LDPE.Pono e hoʻonui ʻia ka ʻāpana make e pale i ka hoʻemi ʻana ma muli o ke kiʻekiʻe o ke kua a me ka haʻihaʻi heheʻe.He 0.024-0.040 i loko a me 0.060-0.10 i loko o ka nui o nā ana o ka LDPE a me LLDPE.
3. Laulā noi maʻamau:
Ua komo ʻo LLDPE i ka hapa nui o nā mākeke kuʻuna no ka polyethylene, me ke kiʻiʻoniʻoni, ka hoʻoheheʻe ʻana, ka paipu, a me ka uea a me ke kaula.ʻO ka mulch anti-leakage kahi mākeke LLDPE hou i kūkulu ʻia.ʻO Mulch, he pepa nui i hoʻokuʻu ʻia i hoʻohana ʻia ma ke ʻano he pae ʻāina a me nā laina wai ʻōpala e pale aku ai i ka ʻike ʻana a i ʻole ka haumia o nā wahi a puni.
ʻO nā laʻana e like me ka hana ʻana i nā ʻeke, ʻeke ʻōpala, ʻeke elastika, nā laina ʻoihana, nā ʻeke kāwele a me nā ʻeke kūʻai, nā mea a pau e hoʻohana i ka ikaika a me ka paʻakikī o kēia resin.ʻO nā kiʻiʻoniʻoni akaka, e like me nā ʻeke berena, ua hoʻomalu ʻia e LDPE no ka maikaʻi o kona hau.
Eia nō naʻe, ʻo ka hui pū ʻana o LLDPE a me LDPE e hoʻomaikaʻi i ka ikaika.ʻO ke kūpaʻa komo ʻana a me ka ʻoʻoleʻa o nā kiʻiʻoniʻoni LDPE me ka ʻole o ka hoʻopilikia nui ʻana i ka mālamalama kiʻiʻoniʻoni.
ʻO ka laulā noi HDPE: nā pahu pahu hau, nā pahu mālama, nā lako kīhini hale, nā uhi hoʻopaʻa, etc.

E hoʻomau ʻia, inā makemake ʻoe e ʻike hou aku, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.ʻO Baiyear kahi hale hana piha piha nui e hoʻohui ana i ka hana ʻana i ka mold plastic, injection molding a me ka hoʻoili metala.A i ʻole hiki iā ʻoe ke hoʻomau i ka hoʻolohe ʻana i ke kikowaena nūhou o kā mākou pūnaewele mana: www.baidasy.com, e hoʻomau mākou i ka hoʻonui ʻana i ka nūhou ʻike e pili ana i ka ʻoihana hoʻoponopono injection.
