Poly(vinyl chloride) Poly(vinyl chloride)

PVC ipurasitiki yepolyvinyl chloride, ruvara rwakajeka, kuramba kwecorrosion, yakasimba uye inogara kwenguva refu, nekuda kwekuwedzera kweplasticizer, anti-aging agent uye zvimwe zvinhu zvine chepfu yekubatsira mukugadzira, saka zvigadzirwa zvayo kazhinji hazvichengete chikafu nemishonga.

PVC inonzi polyvinyl chloride, inova chigadzirwa chepurasitiki chakagadzirwa ne43% oiri uye 57% munyu.Zvichienzaniswa nemamwe marudzi ezvigadzirwa zvepurasitiki, PVC inoshandisa mbishi zvakanyanya uye inoderedza kushandiswa kwemafuta.Panguva imwecheteyo, kushandiswa kwesimba kwePVC kugadzira kwakaderera zvikuru.Uye mukunonoka kushandiswa kwePVC zvigadzirwa, zvinogona kudzokororwa uye kushandurwa kuita zvimwe zvigadzirwa zvitsva kana kupisa kuti uwane simba.

PVC mukugadzira ichawedzera stabilizer, asi iyo stabilizer ine isiri-chepfu uye ine chepfu mapoinzi, chete wedzera lead munyu senge chepfu stabilizer, inoburitsa njodzi dzakavanzika.Asi zvigadzirwa zvePVC zvakasanganiswa, mamwe mabhizinesi madiki anoshandisa lead salt se stabilizer, zvakaoma kuzadzisa akakodzera hutano zviyero.Kana vatengi vakasarudza PVC zvinhu, zviri nani kuenda kumusika wenguva dzose wezvivakwa zvekuvaka uine mukurumbira uye mhando, uye kumbira mutengesi kuti abudise gwaro rekuyedza.Vatengi vanofanirwa kutarisisa kuti vatarise magwaro akakodzera uye mamaki, kuwana "ane chekuita nemvura yekunwa hutano kuchengetedza zvigadzirwa zvehutano rezinesi" zvigadzirwa zvakachengeteka.

UPVC

Yakaoma polyvinyl chloride (UPVC)

UPVC, inozivikanwawo seyakaoma PVC, is amorphous thermoplastic resin yakagadzirwa nevinyl chloride monomer ne polymerization reaction ine zvimwe zvinowedzera (senge stabilizer, lubricant, filler, nezvimwewo).

Pamusoro pekushandisa zvinowedzera, nzira yekubatanidza kugadziridzwa nemamwe marekeni inogamuchirwawo, kuitira kuti ive yakajeka inoshanda kukosha.Aya marenzi CPVC, PE, ABS, EVA, MBS uye zvichingodaro.

Iyo yakanyunguduka viscosity yeUPVC yakakwira uye fluidity haina kunaka.Kunyangwe kana iyo jekiseni kudzvanywa uye kunyunguduka tembiricha yakawedzera, iyo fluidity haizochinja zvakanyanya.Uye zvakare, tembiricha yekugadzira resin iri padyo zvakanyanya nekushisa kwekuora kwekushisa, uye tembiricha yemhando yeresin inogona kuumbwa yakamanikana, saka imhando yezvinhu zvakaoma kuumba.

UPVC pombi fittings, zvakanakira pombi

Huremu: Iyo chikamu cheUPVC zvinhu ingori 1/10 yesimbi yakakandwa, iri nyore kutakura, kuisa uye kuderedza mitengo.

Superior makemikari kuramba: UPVC ine yakanakisa asidhi uye base kuramba, kunze kweasidhi yakasimba uye chigadziko chiri padyo nesaturation point kana yakasimba Oxidising agents atmaximun.

Non-conductive: UPVC zvinhu hazvigone kuitisa magetsi, uye haina corrod ne electrolysis uye ikozvino, saka hapana chikonzero chechipiri chekugadzirisa.

Haikwanise kupisa, kana kutsigira-kupisa, hapana kunetseka kwemoto.

Kuisa nyore, kudhura kwakaderera: kucheka nekubatanidza zviri nyore kwazvo, kushandiswa kwePVC glue yekubatanidza maitiro kwakaratidza kuti ndiyo yakanakisisa kuchengeteka, kushanda nyore, mari shoma.

Durability: Yakanakisa mamiriro ekunze, uye haigone kushatiswa nemabhakitiriya uye fungi.

Kudzikira kuderera, kuyerera kwepamusoro: rusvingo rwemukati rwakatsetseka, kurasikirwa kwemvura kuduku kuduku, tsvina haisi nyore kuomerera kune yakatsetseka chubhu rusvingo, kuchengetedza kuri nyore, mari yekuchengetedza yakaderera.

Polypropylene polypropylene polypropylene polypropylene

PP ipurasitiki yepolypropylene, isina muchetura, isinganakidze, inogona kunyikwa mu100 ℃ mvura inofashaira isina deformation, isina kukuvadzwa, yakajairika acid, alkali organic zvinonyungudutsa zvinenge zvisina mhedzisiro pazviri.Inoshandiswa zvakanyanya pakudya midziyo.

Polypropylene yakaitwa polymerized ne polypropylene monomer.Chinhu chikuru chaiva polypropylene.Zvinoenderana nekuumbwa kwemonomer inotora chikamu mupolymerization, inogona kupatsanurwa kuita marudzi maviri: homogeneous polymerization uye copolymerization.Homopolymer polypropylene ine polymerized kubva kune imwechete propylene monomer uye ine yakakwirira crystallinity, mechanical simba uye kupisa kupisa.Copolymerized polypropylene is copolymerized nekuwedzera zvishoma ethylene monomer.

Zvimiro zvayo zvikuru:

1. Kuonekwa uye maitiro emuviri: ruvara rwechisikigo, cylindrical particles machena uye anopenya, waxy;Isiri-chepfu, isingaravi, inopfuta murazvo yeyero yebhuruu, hutsi hudiki hutema, kunyunguduka kudonha, kunhuwa kweparafini.

2. Kushandiswa kukuru uye kubuda: Iyo polypropylene inounganidzwa mumusika inonyanya kushandiswa kune zvakarukwa zvigadzirwa, zvakanyanya kushandiswa, zvinogona kushandiswa kumabhegi akarukwa, tambo yekurongedza, bhandi rakarukwa, tambo, kapeti inotsigira uye zvichingodaro, kuburitsa kwayo kwegore kune zvinopfuura. 800,000 matani, achiverengera 17% yehuwandu hwekubuda kwepolypropylene.

PE Polyethylene polyethylene

PE ipurasitiki yepolyethylene, yakagadzikana makemikari ehupfumi, inowanzoita mabhegi ezvokudya uye midziyo yakasiyana-siyana, asidhi, alkali uye mvura yemunyu inodzivisa kukukurwa kwemvura, asi haifaniri kupukuta kana kunyudzwa neine alkaline detergent yakasimba.

PPR

Random copolymer polypropylene

1. Nezve Copolymer, copolymer inonzi Homonolymer.A copolymer uyo copolymers kune maviri kana kupfuura monomers anonzi copolymer;

;2. NezvePropylene neEthene, PP-B nePP-R inova Poly poly Copolymer;pakati pavo,

1) Uchishandisa iyo yepamusoro gasi copolymerization process, PE inongoitika uye yakafanana polymerized mu molecular cheni yePP, iyi mbishi inonzi PP-R (random copolymerization polypropylene);

2) Uchishandisa PP uye PE block copolymerization, iyi mbishi zvinhu inonzi PP-B (block copolymerization polypropylene)

PEX

Crosslinked polyethylene (PEX)

Muchinjikwa-yakabatana polyethylene pombi (PEX) pombi sumo

Mapombi epombi akajairika akanyanya density polyethylene (HDPE neMDPE), ane macromolecules ane mutsara, ane dambudziko guru rekushomeka kwekupisa kupisa uye kuramba kunyura, saka mapaipi akajairwa epolyethylene akajairika haakodzere kufambisa svikiro netembiricha inodarika 45 ℃."Cross-linking" inzira yakakosha yekugadziriswa kwe polyethylene.Iyo linear macromolecular chimiro che polyethylene inova PEX ine matatu-dimensional network dhizaini mushure mekuyambuka-yakabatana, iyo inovandudza zvakanyanya kupisa kwekupisa uye kukambaira kuramba kwe polyethylene.Zvichakadaro, kuramba kwayo kuchembera, michina yemagetsi uye kujeka kunovandudzwa zvakanyanya.Panguva imwecheteyo inogara nhaka yezvakazvarwa kemikari ngura kuramba uye kuchinjika kwepombi ye polyethylene.Kune marudzi matatu emachubhu ePEX anotengeswa.PEXa pombi PEXb pombi PEXC pombi

PEX chubhu zvinhu

Yakanakisa kupisa uye kutonhora kuramba, yakakwirira yekupisa simba pakupisa kwakanyanya:

Yakanakisa yakaderera tembiricha kuramba kuoma:

Kupisa pasina kunyungudika:

Zvinoshamisa zvinokambaira kuramba: Creep data hwaro hwakakosha hwekugadzira chigadzirwa uye kusarudzwa kwezvinhu zveinjiniya.Kuenzaniswa nezvinhu zvechinyakare zvakaita sesimbi, hunhu hwemapurasitiki hunoenderana zvakanyanya nenguva yekurodha uye tembiricha.Iyo inokambaira hunhu hwePEX chubhu ingangoita imwe yemapombi akanakisa pakati peakajairika mapaipi epurasitiki.Zvinoshamisa zvinokambaira kuramba: Creep data hwaro hwakakosha hwekugadzira chigadzirwa uye kusarudzwa kwezvinhu zveinjiniya.Kuenzaniswa nezvinhu zvechinyakare zvakaita sesimbi, hunhu hwemapurasitiki hunoenderana zvakanyanya nenguva yekurodha uye tembiricha.Iyo inokambaira hunhu hwePEX chubhu ingangoita imwe yemapombi akanakisa pakati peakajairika mapaipi epurasitiki.

Semi-permanent service life:

Mushure mekunge PEX chubhu yapfuura bvunzo ye110 ℃ tembiricha, 2.5MPa mhete kushushikana uye 8760h nguva, inogona kutariswa kuti inoenderera hupenyu hwesevhisi yemakore makumi mashanu pa70 ℃.
