ʻO ka Rubber a me kāna mau huahana i ke kaʻina hana, mālama a me ka hoʻohana ʻana, ma muli o ka hopena i hui pū ʻia o nā mea i loko a me waho i hoʻokumu ʻia e ka hoʻohaʻahaʻa haʻahaʻa o nā waiwai kino a me nā mea kemika a me nā waiwai mechanical, a hope loa e nalowale ka waiwai hoʻohana, ua kapa ʻia kēia hoʻololi. ʻelemakule lāʻau. Ma luna o ka ʻili, ua māwae, pili, paʻakikī, palupalu, pauda, ​​ʻeleʻele, a me ka maʻi.

ʻO Rigid PVC kekahi o nā mea i hoʻohana nui ʻia. ʻO ka mea PVC kahi mea amorphous.
Hoʻohui pinepine ʻia nā mea PVC i ka hoʻohana maoli ʻana i nā stabilizers, lubricants, auxiliary processing agents, color, impact agents a me nā mea hoʻohui ʻē aʻe.
ʻO ka mea PVC he non-flammability, ikaika kiʻekiʻe, kū i ke aniau a me ke kūpaʻa geometric maikaʻi loa.
He kūpaʻa ikaika ka PVC i nā mea hoʻoheheʻe, nā mea hoʻemi a me nā waikawa ikaika. Eia nō naʻe, hiki ke hoʻopau ʻia e nā ʻakika oxidizing concentrated e like me ka sulfuric acid concentrated, concentrated nitric acid a ʻaʻole kūpono no ka hoʻopili ʻana me nā hydrocarbons aromatic a me nā hydrocarbons chlorinated.

E like me kekahi o nā mea hoʻololi koʻikoʻi koʻikoʻi i ka mākeke plastik honua,CPEhoʻohana nui ʻia i ka hana ʻana i ka extrusion PVC a me nā huahana hoʻoheheʻe ʻia, me ka paʻa PVC profile, nā paipu, nā paipu paipu, nā pepa a me nā panela. Hiki iā ia ke hoʻonui nui i ka ikaika o ka hopena o nā huahana PVC paʻa a hāʻawi i nā huahana i kahi hana haʻahaʻa haʻahaʻa maikaʻi loa, kūpaʻa maikaʻi i ka wā. Hoʻohana ʻia kekahi mau mea kūʻai aku no ka hana ʻana i nā huahana plastik PE a i ʻole PP me ka nui kūpono.

Ke hoʻohālikelike ʻia me nā mea hoʻololi ʻē aʻe e like me AIM (Acrylic Impact Modifier), MBS a me ABS, ʻoi aku ka hoʻokūkū o CPE i kāna mau hana piha a me ke kumukūʻai. Makemake ʻia ʻo CPE e ka nui o nā mea kūʻai aku a ke hoʻonui nei i ka mahele nui o ka mākeke hoʻololi hopena.

ʻO ke ʻano o ka pale anti-corrosion he waiwai nui a he waiwai nui hoʻi kāna kahua noi. ʻO ke kiʻekiʻe chlorinated polyethylene pipeline anticorrosive coating ʻo ia kekahi o ka papa o ka polyethylene resin chlorinated kiʻekiʻe e like me ka mea anticorrosive base, me ka resin i hoʻololi ʻia, plasticizer, pigments rust, solvents a me nā mea hoʻohui i hoʻokumu ʻia i hoʻokahi mea hoʻokahi uhi anticorrosive kaumaha.

ʻO ka lāʻau lapaʻau he pilikia pinepine i ka hana ʻana o ke kaula polyethylene chlorinated, a ʻoi aku ka kaulana o kēia ʻano i ke kauwela. ʻO nā mea e hoʻoulu ai i ka wela extrusion, ke kaomi mahu, ka manawa coke o ka hui ʻana i ka lāʻau, a me ka hui ʻana o nā haumia.

Loaʻa i ka chlorinated polyethylene kekahi mau hiʻohiʻona o nā plastics, a ke hoʻohana ʻia no ka extrusion uwea, pono ia i kahi mahana plasticizing kiʻekiʻe ma mua o ka lāʻau kuʻuna. No nā mea kūʻai i ʻike ʻole i nā ʻano o ka CPE, inā ʻaʻole lākou e ʻike i ke kaʻina hana kūpono a hahai i ke kaʻina hana extrusion rubber maʻamau e hana i nā kaula, hiki mai nā pilikia e like me ka haʻahaʻa haʻahaʻa a me ka plasticization maikaʻi ʻole.

ʻO ka polyethylene chlorinated ka pauka, maʻalahi ke komo i ka makū no ka manawa lōʻihi, ka hopena i ka nui o ka wai, i loaʻa i nā huahana nā ʻōpū a i ʻole micropores, a me nā mea ʻē aʻe, ʻoi aku ka nui o kēia ʻano. Eia kekahi, ʻoi aku ka paʻakikī o ka hana ʻana i nā kaula hao ma mua o nā kaula plastik, i hoʻopili ʻia e nā kumu he nui e like me nā kūlana o nā mea hana, nā kūlana kaʻina hana, ka pae hana, ka pae ʻenehana, a me nā mea ʻē aʻe, ʻoi aku ka nui o nā pilikia i ke kaʻina extrusion, a ʻo ia. ʻaʻole maʻalahi e hoʻoponopono pono.

ʻO ka Polyethylene (PE) kekahi o nā resins synthetic nui ʻelima, ua māhele nui ʻia ka polyethylene i ka linear low density polyethylene (LLDPE), low density polyethylene (LDPE), high density polyethylene (HDPE) ʻekolu mau ʻāpana. ʻO nā ʻano nui i hoʻololi ʻia o ka polyethylene he chlorinated polyethylene, chlorosulfonated polyethylene, crosslinked polyethylene a me nā ʻano like ʻole i hoʻololi ʻia.

ʻO Rutile titanium dioxide a me anatase titanium dioxide nā ʻano koʻikoʻi ʻelua o ka titanium dioxide, ʻo ia ka mea i hoʻohana nui ʻia i ka mākeke, akā ʻokoʻa loa nā waiwai o nā mea ʻelua.

ʻO ACR ka mea hoʻololi hoʻololi maikaʻi loa me ka hana holoʻokoʻa maikaʻi, ka hana hoʻoponopono maikaʻi o ka PVC i hoʻololi ʻia, ka ikaika tensile kiʻekiʻe, ka modulus, ka wela deformation wela, a me ke kūpaʻa maikaʻi loa. Ma waho aʻe o ka maikaʻi ʻole o ka wā, ʻo MBS kekahi mea hoʻololi i ka hopena PVC me ka hana holoʻokoʻa maikaʻi, ʻoi aku ka nui o ka MBS i kahi kuhikuhi refractive e like me PVC, a ʻo ia wale nō ka mea hoʻololi hopena i hoʻohana ʻia no ka hana ʻana i nā huahana PVC i hoʻololi ʻia.

Hoʻohana nui ʻia ʻo CPVC i nā ʻano huahana extruded: paipu, papa, profiles, sheets, etc. ʻO kāna noi ʻo ia ka mea nui o kekahi ʻoihana kemika corrosion kaiapuni, nā wahi me nā koi pale ahi, a me nā manawa me nā koi pale wela, a me ka hana o PVC maʻamau. ʻAʻole hiki i ka resin ke hoʻokō i nā koi.
