(8).PP (polypropylene)
1. Ka hana a PP
ʻO PP kahi polymer kiʻekiʻe crystalline.Ma waena o nā plastics maʻamau, ʻo PP ka māmā, me ka nui o 0.91g/cm3 wale nō (ʻoi aku ka liʻiliʻi ma mua o ka wai).Ma waena o nā plastics maʻamau, ʻoi aku ka maikaʻi o ka pale ʻana o ka wela, ʻo 80-100 ℃ kona wela wela, a hiki ke hoʻolapalapa ʻia i ka wai paila.He maikaʻi ko PP i ke koʻikoʻi o ka haʻihaʻi ʻana a me ke ola luhi flexural kiʻekiʻe, i ʻike mau ʻia ʻo "folding glue".
ʻOi aku ka maikaʻi o ka hana piha o ka PP ma mua o ka mea PE.ʻO nā huahana PP he māmā ke kaumaha, ka paʻakikī maikaʻi a me ke kūpaʻa kemika maikaʻi.ʻO nā hemahema o ka PP: ka haʻahaʻa haʻahaʻa, ʻaʻole lawa ka rigidity, ke kū ʻana o ka wā maikaʻi ʻole, maʻalahi ka hana ʻana i ka "pōʻino keleawe", loaʻa iā ia ke ʻano o ka post-shrinkage, a ma hope o ka demolding, ua maʻalahi ka makahiki, lilo i brittle, a maʻalahi hoʻi e deform.ʻO PP ka mea kumu nui no ka hana ʻana i nā fiber ma muli o kona hiki ke kala, abrasion a me nā waiwai kūʻē kemika, a me nā kūlana waiwai maikaʻi.
ʻO PP kahi mea semi-crystalline.ʻOi aku ka paʻakikī a ʻoi aku ka nui o ka heheʻe ma mua o ka PE.No ka mea he palupalu loa ka homopolymer PP ma nā mahana ma luna o 0 °C, he nui nā mea PP pāʻoihana he copolymers maʻamau me ka 1 a 4% ethylene i hoʻohui ʻia a i ʻole nā copolymers pincer me nā mea ethylene kiʻekiʻe.ʻO ka mea copolymer-type PP he haʻahaʻa haʻahaʻa haʻahaʻa wela (100 ° C), haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, haʻahaʻa rigidity, akā ʻoi aku ka ikaika o ka hopena.Hoʻonui ka ikaika o PP me ka hoʻonui ʻana i ka ʻike ethylene.
ʻO ka mahana hoʻonāwaliwali o Vicat o PP he 150°C.Ma muli o ke kūlana kiʻekiʻe o ka crystallinity, ʻoi aku ka maikaʻi o ka ʻili o kēia mea a me nā waiwai kūʻē.
ʻAʻole loaʻa iā PP nā pilikia hoʻoluhi kaiapuni.ʻO ka maʻamau, hoʻololi ʻia ʻo PP ma o ka hoʻohui ʻana i nā fibers aniani, nā mea hoʻohui metala a i ʻole nā mea wela thermoplastic.ʻO ka kahe kahe MFR o PP mai ka 1 a hiki i ka 40. ʻO nā mea PP me ka MFR haʻahaʻa i ʻoi aku ka maikaʻi o ka hopena hopena akā haʻahaʻa haʻahaʻa.No ka mea MFR like, ʻoi aku ka ikaika o ka ʻano copolymer ma mua o ka ʻano homopolymer.
Ma muli o ka crystallization, he kiʻekiʻe ka shrinkage rate o PP, maʻamau 1.8 ~ 2.5%.A ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana o ka shrinkage ma mua o nā mea e like me HDPE.ʻO ka hoʻohui ʻana i ka 30% aniani additive hiki ke hōʻemi i ka shrinkage i 0.7%.
Loaʻa i nā mea homopolymer a me ka copolymer PP ka maikaʻi o ka hoʻoheheʻe ʻana i ka wai, ka ʻakika a me ke kūpaʻa alkali, a me ke kūpaʻa solubility.Eia naʻe, ʻaʻole ia e kūʻē i nā mea hoʻoheheʻe aromatic hydrocarbon (e like me benzene), chlorinated hydrocarbon (carbon tetrachloride) solvents, etc. ʻAʻole like ka PP i ka pale ʻana i ka oxidation ma nā wela kiʻekiʻe e like me PE.
2. Kaʻina hana o PP
He maikaʻi ka wai o ka PP ma ka wela hoʻoheheʻe a me ka hana hoʻoheheʻe maikaʻi.ʻElua mau hiʻohiʻona ʻo PP i ka hana ʻana:
Hoʻokahi: Ke emi nui nei ka viscosity o PP hehee me ka piʻi ʻana o ka shear rate (ua emi ka hopena o ka wela);
ʻO ka lua: he kiʻekiʻe ke kiʻekiʻe o ka orientation molecular a he nui ka nui o ka emi ʻana.ʻO ka mahana hana o PP he 220 ~ 275 ℃.ʻOi aku ka maikaʻi ʻaʻole ma mua o 275 ℃.Loaʻa iā ia ke kūpaʻa wela maikaʻi (ʻo 310 ℃ ka wela decomposition), akā i ka wela kiʻekiʻe (270-300 ℃), e noho lōʻihi ia i loko o ka pahu.Aia kahi hiki ke hoʻohaʻahaʻa.Ma muli o ka emi ʻana o ka viscosity o PP me ka piʻi ʻana o ka wikiwiki shear, hoʻonui i ke kaomi injection a me ka wikiwiki o ka injection e hoʻomaikaʻi i kona wai a hoʻomaikaʻi i ka deformation shrinkage a me ke kaumaha.ʻO ka mahana wela (40 ~ 80 ℃), 50 ℃ ua ʻōlelo ʻia.
Hoʻoholo nui ʻia ka degere o ka crystallization e ka mahana o ka mold, pono e mālama ʻia i loko o ka laulā o 30-50 °C.Hiki i ka hoʻoheheʻe PP ke hele i kahi ākea make haiki loa a ʻike ʻia he draped.I ka wā o ka hoʻoheheʻe ʻana o PP, pono ia e komo i ka nui o ka wela fusion (ʻoi aku ka wela kikoʻī nui), a ʻoi aku ka wela o ka huahana ma hope o ka hoʻokuʻu ʻia ʻana mai ka ʻōpala.
ʻAʻole pono e hoʻomaloʻo ʻia nā mea PP i ka wā e hana ai, a ʻoi aku ka haʻahaʻa o ka shrinkage a me ka crystallinity o PP ma mua o ka PE.Hiki ke hoʻohana ʻia ka wikiwiki kiʻekiʻe e hoʻemi i ke kaomi kūloko.Inā loaʻa nā hemahema ma ka ʻili o ka huahana, a laila pono e hoʻohana ʻia ka haʻahaʻa haʻahaʻa haʻahaʻa i nā mahana kiʻekiʻe.ʻO ke kaomi injection: a hiki i 1800bar.
