Poly(vinyl chloride) Poly(vinyl chloride)

ʻO PVC ka polyvinyl chloride plastic, ke kala ʻulaʻula, ke kūpaʻa ʻana i ka corrosion, paʻa a paʻa, ma muli o ka hoʻohui ʻana o ka plasticizer, anti-aging agent a me nā mea ʻona ʻē aʻe i ke kaʻina hana, no laila ʻaʻole mālama nā huahana i nā meaʻai a me nā lāʻau lapaʻau.

ʻO ka PVC he polyvinyl chloride, he huahana plastik i hana ʻia me 43% aila a me 57% paʻakai.Ke hoʻohālikelike ʻia me nā ʻano huahana plastik ʻē aʻe, hoʻohana ʻo PVC i nā mea maka i ʻoi aku ka maikaʻi a hoʻemi i ka ʻai wahie.I ka manawa like, haʻahaʻa loa ka hoʻohana ʻana i ka ikehu o ka hana PVC.A i ka hoʻohana hope ʻana o nā huahana PVC, hiki ke hana hou ʻia a hoʻololi ʻia i nā huahana hou a i ʻole incineration e loaʻa ai ka ikehu.

ʻO ka PVC i ka hana e hoʻohui i ka stabilizer, akā ʻo ka stabilizer he mau mea ʻawaʻawa a me nā mea ʻawaʻawa, hoʻohui wale i ka paʻakai kepau e like me ka stabilizer toxic, e hoʻopuka i nā pōʻino huna.Akā ua hui pū ʻia nā huahana PVC, hoʻohana kekahi mau ʻoihana liʻiliʻi i ka paʻakai paʻakai ma ke ʻano he stabilizer, paʻakikī ke hoʻokō i nā kūlana olakino pili.Ke koho nā mea kūʻai aku i nā mea PVC, ʻoi aku ka maikaʻi o ka hele ʻana i ka mākeke mea hale maʻamau me ka maikaʻi a me ka maikaʻi, a noi i ka mea hoʻolako e hoʻopuka i kahi hōʻike hōʻike.Pono nā mea kūʻai aku e nānā i nā palapala kūpono a me nā hōʻailona, ​​​​e loaʻa i nā huahana "pili i ka wai inu wai palekana palekana olakino" nā huahana palekana.

UPVC

Polyvinyl chloride paʻakikī (UPVC)

ʻO UPVC, i kapa ʻia ʻo PVC paʻakikī, he resin thermoplastic amorphous i hana ʻia me ka vinyl chloride monomer e ka polymerization reaction me kekahi mau mea hoʻohui (e like me ka stabilizer, lubricant, filler, etc.).

Ma kahi o ka hoʻohana ʻana i nā mea hoʻohui, ua ʻae ʻia ke ʻano o ka hoʻohui ʻana i ka hoʻololi me nā resins ʻē aʻe, i ʻike ʻia ka waiwai kūpono.ʻO kēia mau resins he CPVC, PE, ABS, EVA, MBS a pēlā aku.

He kiʻekiʻe ka hoʻoheheʻe viscosity o UPVC a maikaʻi ʻole ka wai.ʻOiai inā e hoʻonui ʻia ke kaomi injection a me ka wela heheʻe, ʻaʻole e loli nui ka wai.Eia kekahi, kokoke loa ka mahana o ka resin i ka wela decomposition thermal, a hiki ke hana ʻia ke ʻano wela o ka resin he haiki loa, no laila he ʻano mea paʻakikī ke hana.

ʻO nā pono paipu UPVC, nā pono o ka paipu

Māmā: ʻO ka hapa o nā mea UPVC he 1/10 wale nō o ka hao hao, maʻalahi ke lawe, hoʻokomo a hoʻemi i nā kumukūʻai.

ʻO ke kūpaʻa kemika kiʻekiʻe: He ʻakika maikaʻi loa ka UPVC a me ke kūpaʻa kumu, koe wale nō ka waikawa ikaika a me ke kumu kokoke i ka wahi saturation a i ʻole nā ​​​​mea hana Oxidising ikaika atmaximun.

Non-conductive: ʻAʻole hiki i nā mea UPVC ke alakaʻi i ka uila, ʻaʻole i ʻino ʻia e ka electrolysis a me kēia manawa, no laila ʻaʻohe pono no ka hana lua.

ʻAʻole hiki ke puhi ʻia, ʻaʻole hoʻi e kākoʻo i ke ahi, ʻaʻohe pilikia ahi.

Hoʻokomo maʻalahi, kumukūʻai haʻahaʻa: ʻo ka ʻoki a me ka hoʻopili ʻana he mea maʻalahi loa, ʻo ka hoʻohana ʻana i ka hana hoʻopili PVC glue ua hōʻoia ʻia ʻo ia ka palekana maikaʻi loa, ka hana maʻalahi, ka uku haʻahaʻa.

Ka lōʻihi: ʻOi aku ka maikaʻi o ka weatherability, a ʻaʻole hiki ke hoʻopōʻino ʻia e ka bacteria a me nā haʻi.

ʻO ke kūpaʻa haʻahaʻa, ke kahe kahe kiʻekiʻe: ʻoluʻolu ka paia o loko, liʻiliʻi ke kahe o ka wai, ʻaʻole maʻalahi ka lepo e pili i ka paia o ka paipu, maʻalahi ka mālama, haʻahaʻa ke kumukūʻai mālama.

Polypropylene polypropylene polypropylene polypropylene

ʻO PP ka polypropylene plastic, non-toxic, tasteless, hiki ke hoʻomoʻi ʻia i ka 100 ℃ ka wai paila me ka ʻole o ka deformation, ʻaʻohe pōʻino, ka waikawa maʻamau, nā mea hoʻoheheʻe organik alkali aneane ʻaʻohe hopena.Hoʻohana nui ʻia no nā mea ʻai.

Hoʻopili ʻia ka polypropylene e ka polypropylene monomer.ʻO ka mea nui he polypropylene.E like me ke ʻano o ka monomer e komo ana i ka polymerization, hiki ke hoʻokaʻawale ʻia i ʻelua ʻano: homogeneous polymerization a me copolymerization.Homopolymer polypropylene ua polymerized mai hoʻokahi propylene monomer a he kiʻekiʻe crystallinity, mechanical ikaika a me ka wela.Hoʻopili ʻia ka polypropylene copolymerized ma ka hoʻohui ʻana i kahi mea liʻiliʻi o ka ethylene monomer.

ʻO kāna mau hiʻohiʻona nui:

1. Nā hiʻohiʻona a me nā hiʻohiʻona kino: ke kala maoli, nā ʻāpana cylindrical keʻokeʻo a translucent, waxy;ʻAʻohe mea ʻawaʻawa, ʻono ʻole, ʻaʻa ahi melemele uliuli, kahi wahi o ka uahi ʻeleʻele, kulu hehee, ʻala paraffin.

2. ʻO ka hoʻohana nui a me ka huahana: ʻO ka polypropylene i hōʻiliʻili ʻia ma ka mākeke e hoʻohana nui ʻia no nā huahana i ulana ʻia, hoʻohana nui ʻia, hiki ke hoʻohana ʻia no nā ʻeke i ulana ʻia, ke kaula hoʻopili, ke kāʻei i ulana ʻia, ke kaula, ke kākoʻo kāpeti a pēlā aku. 800,000 tons, helu no 17% o ka huina pau o ka polypropylene.

PE Polyethylene polyethylene

ʻO PE ka polyethylene plastic, paʻa kemika waiwai, hana maʻamau i nā ʻeke meaʻai a me nā ipu like ʻole, ka waika, ka alkali a me ka wai paʻakai e pale ʻia, akā ʻaʻole pono e holoi ʻia a pulu ʻia me ka mea holoi alkaline ikaika.

PPR

ʻO ka polypropylene copolymer random

1. No ka Copolymer, ua kapaia ka copolymer he Homonolymer.ʻO ka copolymer nāna i kope i nā monomer ʻelua a ʻoi aku paha i kapa ʻia he copolymer;

;2. No ka Propylene a me Ethene, lilo ka PP-B a me PP-R i Poly poly Copolymer;iwaena o lakou,

1) Ke hoʻohana nei i ke kaʻina hana copolymerization kinoea kiʻekiʻe, ua paʻa ʻole ʻia ʻo PE i loko o ke kaulahao mole o PP, ua kapa ʻia kēia mea maka he PP-R(polypropylene copolymerization random);

2) Ke hoʻohana nei i ka PP a me ka PE block copolymerization, ua kapa ʻia kēia mea maka he PP-B (block copolymerization polypropylene)

PEX

Polyethylene i hoʻopaʻa ʻia (PEX)

Hoʻokomo ʻia ka paipu polyethylene paipu (PEX).

ʻO nā paipu polyethylene kiʻekiʻe kiʻekiʻe (HDPE a me MDPE), nona nā macromolecules linear, ʻoi aku ka maikaʻi ʻole o ka pale ʻana i ka wela a me ka pale ʻana, no laila ʻaʻole kūpono nā paipu polyethylene kiʻekiʻe kiʻekiʻe maʻamau no ka lawe ʻana i ka medium me kahi mahana ʻoi aku ma mua o 45 ℃.ʻO ka "cross-linking" kahi ala nui no ka hoʻololi ʻana i ka polyethylene.ʻO ka linear macromolecular structure o ka polyethylene e lilo i PEX me ka ʻoihana pūnaewele ʻekolu-dimensional ma hope o ka hoʻopili ʻana, kahi e hoʻomaikaʻi nui ai i ka pale wela a me ka pale ʻana o ka polyethylene.I kēia manawa, hoʻomaikaʻi maikaʻi ʻia kona kūpaʻa ʻelemakule, nā waiwai mechanical a me ka transparency.I ka manawa like, loaʻa iā ia ke kūpaʻa kino a me ka maʻalahi o ka paipu polyethylene.ʻEkolu ʻano o nā paipu PEX i kūʻai ʻia.PEXa paipu PEXb paipu PEXC paipu

Nā hiʻohiʻona paipu PEX

ʻOi aku ka maikaʻi o ka wela a me ke anu, ka ikaika wela kiʻekiʻe i ka wela kiʻekiʻe:

ʻOi aku ka ikaika haʻahaʻa haʻahaʻa haʻahaʻa:

Pumehana me ka hehee ole:

Kū'ē kū'ē kū'ē: He kumu koʻikoʻi ka ʻikepili creep no ka hoʻolālā huahana a me ke koho ʻana i nā mea ʻenehana.Ke hoʻohālikelike ʻia me nā mea kuʻuna e like me nā metala, ʻo ke ʻano o ka palaka i hilinaʻi nui ʻia i ka manawa hoʻouka a me ka mahana.ʻO ka hiʻohiʻona o ka paipu PEX kahi o nā paipu maikaʻi loa ma waena o nā paipu plastik maʻamau.Kū'ē kū'ē kū'ē: He kumu koʻikoʻi ka ʻikepili creep no ka hoʻolālā huahana a me ke koho ʻana i nā mea ʻenehana.Ke hoʻohālikelike ʻia me nā mea kuʻuna e like me nā metala, ʻo ke ʻano o ka palaka i hilinaʻi nui ʻia i ka manawa hoʻouka a me ka mahana.ʻO ka hiʻohiʻona o ka paipu PEX kahi o nā paipu maikaʻi loa ma waena o nā paipu plastik maʻamau.

Ke ola lawelawe Semi-permanent:

Ma hope o ka hala ʻana o ka paipu PEX i ka hoʻāʻo o 110 ℃ wela, 2.5MPa apo kaumaha a me 8760h manawa, hiki ke unuhi ʻia ʻo kona ola mau ʻana o 50 mau makahiki ma 70 ℃.
