Pombi yepurasitiki chinhu chakajairika chepombi chave chichishandiswa zvakanyanya muminda yakawanda nekuda kwepurasitiki yayo, mutengo wakaderera, uremu, uye corrosion resistance. Izvi zvinotevera zvakati wandei zvakajairika epurasitiki pombi zvinhu uye nzvimbo dzekushandisa uye mabasa:

PVC pombi:pombi yepolyvinyl chloride (PVC) ndeimwe yezvinhu zvakanyanya kushandiswa pombi uye inogona kushandiswa kumvura, gasi, tsvina, kushandiswa kwemaindasitiri, etc. PVC pombi ine corrosion resistance, pressure resistance, chisimbiso chakanaka, mutengo wakaderera, zvichingodaro.

PE pombi:polyethylene (PE) pombi zvakare yakajairika pombi zvinhu, kunyanya kushandiswa mumvura, gasi, tsvina, etc. PE pombi ine kukanganisa kupikisa, kushorwa kwegora, kushanduka kwakanaka, zvichingodaro.

PP-R pombi:polypropylene random copolymer (PP-R) pombi inogona kushandiswa mukati meimba yekugovera mvura masisitimu, kupisa kwepasi, firiji, etc. PP-R pombi ine yakakwirira-tembiricha kuramba, asidhi, uye alkali kuramba, haisi nyore kuyera, uye saka. on.

ABS pombi:ABS pombi inodzivirira-inodzivirira, corrosion-resistant pombi zvinhu, inonyanya kushandiswa mukuchenesa tsvina, tsvina yemukicheni, uye mimwe minda.

PC pipe:polycarbonate (PC) pombi ine simba rakawanda, kujeka kwepamusoro, uye humwe hunhu, uye inogona kushandiswa mumigwagwa mikuru, tunnels, subways, nedzimwe nzvimbo dzekuvaka.

PA pipe:polyamide (PA) pombi inonyanya kushandiswa mumunda wemhepo, oiri, mvura, uye zvimwe zvinwiwa zvekutakura.PA pombi inodzivirira ngura, inodzivirira kupisa, inodzivirira kumanikidza, uye humwe hunhu.

Yakasiyana epurasitiki pombi zvinhu zvakakodzera minda yakasiyana. Kazhinji, mapaipi epurasitiki ane zvakanakira kuve akareruka, mutengo wakaderera, usingadziviriri, wakanakira kuvaka, nezvimwewo, uye zvishoma nezvishoma unotsiva mapaipi esimbi echinyakare, uye anoita basa rinowedzera kukosha mukuvaka kwemazuva ano.

Nekudaro, mamwe matambudziko akajairika anogona kusangana panguva yekugadzira uye kugadzirisa mapaipi epurasitiki, kusanganisira:

Kunyungudika kusina kunaka:zvimwe zvinhu zvepurasitiki zvakasvibirira mukugadzirisa, nekuda kwechimiro chemakemikari cheni uye zvimwe zvinhu, zvinogona kutungamira kune kunyungudika kunyungudika, zvichikonzera kusaenzana kwekuzadza muextrusion kana jekiseni molding process, kusagutsikana kwepamusoro mhando, uye mamwe matambudziko.

Pakaipa dimensional kugadzikana:mamwe epurasitiki mbishi zvinhu mukugadzirisa uye kutonhora maitiro shrinkage, zviri nyore kutungamira kune hurombo dhimensional kugadzikana kwechigadzirwa chakapedzwa, kana kunyange deformation uye mamwe matambudziko.

Hunhu husina kunaka:Mukuita extrusion kana jekiseni molding, nekuda kwekusanzwisisika dhizaini ye molds, kutadza kutonga kwekunyunguduka kunyunguduka, nezvimwewo, zvinogona kutungamira kune zvikanganiso senge kusaenzana, mabhubhu, kuteedzera, nezvimwewo pamusoro pezvigadzirwa zvakapedzwa.

Kusakwanisa kupisa kupisa:mamwe epurasitiki mbishi zvinhu zvinowanzopfava nekuremara pakupisa kwepamusoro, izvo zvingave dambudziko kune pombi yekushandisa inoda kushingirira kutonhora kwakanyanya.

Kusakwana tensile simba:mamwe epurasitiki mbishi zvinhu hazvina simba rakakwirira pachazvo, zvichiita kuti zviome kuzadzisa zvinodikanwa zvekusimba kwesimba mune mamwe mainjiniya ekushandisa.

Aya matambudziko anogona kazhinji kugadziriswa nekuvandudza maumbirwo ezvakagadzirwa, kukwenenzvera nzira dzekugadzirisa, nekuvandudza dhizaini yekuumbwa. Panguva imwecheteyo, zvinogoneka zvakare kuwedzera akakosha ekusimbisa maajenti, mafirita, mafuta ekuzora, uye zvimwe zvikamu zvekubatsira kuvandudza mashandiro ekugadzirisa mapaipi epurasitiki uye kunaka kwechigadzirwa chakapedzwa. Kwemakore akawanda, PPA (Polymer Processing Additive) fluoropolymer kugadzirisa aids yakasarudzwa nevazhinji vanogadzira pombi semafuta.

PPA (Polymer Processing Additive) fluoropolymer processing additives mukugadzira pombi inonyanya kushandiswa kuvandudza mashandiro ekugadzirisa, kuvandudza mhando yezvigadzirwa zvakapedzwa, uye kuderedza mari yekugadzira. Kazhinji iripo muchimiro chemafuta ekuzora, uye inogona kunyatso dzikisa frictional kuramba, uye kuvandudza kunyunguduka kunyunguduka uye kuzadza kwepurasitiki, nekudaro kuvandudza kugadzirwa uye kunaka kwechigadzirwa mu extrusion kana jekiseni molding process.

Pasi rose, PFAS inoshandiswawo zvakanyanya mumaindasitiri mazhinji uye nevatengi zvikumbiro, asi njodzi dzinogona kuitika kune zvakatipoteredza uye hutano hwevanhu zvakakonzera kushushikana kwakapararira. NeEuropean Chemicals Agency (ECHA) ichiita kuti zvirambidzo zvePFAS zvive pachena muna 2023, vagadziri vazhinji vari kutanga kutsvaga dzimwe nzira dzePPA fluoropolymer processing aids.

Kupindura kune zvinodiwa pamusika nemhinduro itsva——SILIKE InotangisaPFAS-Yemahara Polymer Processing Aid (PPA)

Mukupindura maitiro enguva, SILIKE's R&D timu yakaisa mari yakawanda yekuedza mukugadzira.PFAS-yemahara polymer kugadzirisa aids (PPAs)kushandisa yazvino tekinoroji nzira uye kufunga kwekuvandudza, kuita mupiro wakanaka mukuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba.

SILIKE Fluorine-Yemahara PPAinodzivirira njodzi dzezvakatipoteredza uye dzehutano dzine chekuita neyakajairwa PFAS makomisheni uku uchiona magadzirirwo ekuita uye kunaka kwezvinhu.SILIKE Fluorine-Yemahara PPAhaingoenderane chete nezvirango zvePFAS zvakaburitswa neECHA asi zvakare inopa yakachengeteka uye yakavimbika imwe nzira kune yechinyakare PFAS makomputa.

SILIKE Fluorine-Yemahara PPAndeye PFAS-yemahara polymer yekugadzirisa rubatsiro (PPA) kubva kuSILIKE. Iyo yekuwedzera ndeye organically yakagadziridzwa polysiloxane chigadzirwa chinotora mukana weakanakisa ekutanga lubrication maitiro epolysiloxanes uye polarity yemapoka akagadziridzwa kutamira uye kuita pamichina yekugadzirisa panguva yekugadzirisa.

SILIKE Fluorine-Yemahara PPA inogona kutsiva yakakwana yefluorine-yakavakirwa PPA kugadzirisa aids. Kuwedzera zvishoma zveSILIKE Fluorine-Yemahara PPA SILIMER 5090,SILIMER 5091inogona kunyatso kuvandudza resin fluidity, processability, lubrication, uye pamusoro pezvimiro zvepurasitiki extrusion, kubvisa kunyunguduka kunyunguduka, kunatsiridza kupfeka kuramba, kuderedza coefficient yekupokana, uye kuvandudza goho uye mhando yechigadzirwa uchinge uine hushamwari uye hwakachengeteka.

Basa reSILIKE Fluorine-Yemahara PPA SILIMER 5090mukugadzira pombi dzepurasitiki:

Kuderedzwa kwemukati nekunze kwedhayamitakusiyana: Mune extrusion process yepombi, kuwirirana kwemukati nekunze kwemadhayamita kwakakosha zvikuru. Kuwedzera kweSILIKE Fluorine-Yemahara PPA SILIMER 5090inoderedza kupokana pakati pekunyunguduka uye kufa, inoderedza mukati nekunze dhayamita misiyano, uye inova nechokwadi chekugadzikana kwepombi.

Kugadziriswa kwepamusoro pekupedzisira:SILIKE Fluorine-Yemahara PPA SILIMER 5090zvinonyatso gadzirisa kupera kwepombi, uye kuderedza kushushikana kwemukati uye kunyunguduka masara, zvichiita kuti pave nepombi yakatsetseka ine maburrs mashoma uye mavanga.

Lubricity yakavandudzwa:SILIKE Fluorine-Yemahara PPA SILIMER 5090inoderedza kunyunguduka kwemapurasitiki uye inonatsiridza lubricity, zvichiita kuti zvive nyore kuyerera uye kuzadza mold, nekudaro kuwedzera chibereko muextrusion kana jekiseni molding maitiro.

Kubviswa kwekunyunguduka kwemelt:Kuwedzera kweSILIKE Fluorine-Yemahara PPA SILIMER 5090inoderedza coefficient of friction, inoderedza torque, inovandudza mukati nekunze lubrication, zvinobudirira kubvisa kunyunguduka kunyunguduka, uye inowedzera hupenyu hwebasa hwepombi.

Yakavandudzwa kupfeka kuramba: SILIKE Fluorine-Yemahara PPA SILIMER 5090inovandudza abrasion resistance yepombi, ichiita kuti ive yakanyatsokodzera kune zvikumbiro zvinoda yakakwira abrasion resistance.

Kuderedza kushandiswa kwesimba:Nekuda kwekugona kwayo kudzikisa kunyunguduka viscosity uye frictional resistance,SILIKE Fluorine-Yemahara PPAinoderedza kushandiswa kwesimba panguva yeextrusion kana jekiseni molding, nekudaro ichidzikisa mutengo wekugadzira.

SILIKE Fluorine-Yemahara PPAine zvakasiyana-siyana zvekushandisa, kwete zvemachubhu chete asiwo waya netambo, mafirimu, masterbatches, petrochemicals, metallocene polypropylene (mPP), metallocene polyethylene (mPE), nezvimwewo. Nekudaro, maapplication chaiwo anofanirwa kugadziridzwa uye kukwenenzverwa zvinoenderana neakasiyana zvinhu uye zvinodiwa zvekugadzira. Kana iwe uine chero mibvunzo nezve chero chezvishandiso zviri pamusoro, SILIKE inofara kwazvo kugamuchira kubvunza kwako, uye isu tine shungu yekuongorora dzimwe nzvimbo dzekushandisa dzePFAS-yemahara polymer processing aids (PPA) newe.
