Nhanganyaya yeWaya dzePVC dzine Utsi Hwakaderera uye Makomputa eCable
Waya dzePVC (Polyvinyl Chloride) dzine utsi hushoma uye tambo dzakagadzirwa ne thermoplastic dzakagadzirwa kuderedza utsi nemhepo ine chepfu panguva yekutsva. Izvi zvinoita kuti dzive sarudzo yakakosha pakushandiswa uko kuchengetedzeka pamoto kuri chinhu chinonyanya kukosha. Dzinowanzo shandiswa pakudzivirira kupisa uye kuputira tambo dzemagetsi, tambo idzi dzine zvinhu zvakakosha:
Kuumbwa:Makomputa ePVC asina utsi hwakawanda anogadzirwa nemusanganiswa wePVC resin, mapurasitiki (akadai sedioctyl phthalate uye tri-2-ethylhexyl trimellitate), zvinodzivisa moto (semuenzaniso, antimony trioxide, aluminium trihydrate, uye zinc borate), zvinosimbisa (calcium/zinc-based), zvinozadza (calcium carbonate), uye mafuta anonhuhwirira.
Hunhu Husina Utsi Hwakawanda:Kusiyana nePVC yakajairwa, iyo inogona kuderedza kuonekwa kusvika ku90% mumaminitsi makumi matatu chete nekuda kweutsi hwakawanda, makemikari ePVC ane utsi hushoma akagadzirwa kuti asvike padanho rekuchengetedza rakaita seBS EN 61034. Mishonga iyi inobvumira kanenge 60% yekufambisa chiedza panguva yekutsva, zvichivandudza zvikuru kuchengetedzeka.
Kudzivirira Murazvo: PVC ine hunhu hunodzivirira moto nekuda kwehuwandu hwechlorine, iyo inowedzera nezvimwe zvinowedzera zvinodzivirira moto. Mishonga iyi inosangana nezvinodiwa zvakasimba seIEC 60332-1-2, UL VW1, uye E84 (flame spread index <25, smoke developed index <50).
Mashandisirwo:Zvinowanzoshandiswa munzvimbo dzine njodzi huru dzakadai senzvimbo dzedata, matunnel, ndege, marori echitima, uye zvivakwa zveveruzhinji, waya dzePVC dzine utsi hushoma uye tambo dzakakosha pakuderedza njodzi dzinosanganisirwa neutsi nehutsi hune chepfu kana pakaitika moto.
Matambudziko Akajairika Ekugadzirisa uye Mhinduro dzeWaya dzePVC Dzisina Utsi Hwakawanda uye Makomputa Etambo
Kugadzira mishonga yePVC ine utsi hushoma kunosanganisira kugadzirisa matambudziko akasiyana-siyana, kunyanya nekuda kwekugadzirwa kwayo kwakaoma. Pazasi, tinokurukura mamwe ematambudziko anowanzo shandiswa pakugadzirisa uye mhinduro dzawo:
1. Zviri Mukati Memafuta Akawanda Zvinokonzera Kusafamba Zvakanaka Uye Kufamba Kwakanyanya
Dambudziko:Kuti pave nehutsi hushoma, maPVC compounds anowanzo kuve nehuwandu hwakawanda hwezvinhu zvisingasanganisike zvakaita sealuminium trihydrate (ATH) kana magnesium hydroxide (Mg(OH)₂) — kazhinji huremu hwe20-60%. Kunyange zvazvo zvinhu izvi zvichideredza utsi nemurazvo, zvinogona kuwedzera viscosity, kuderedza kufamba kwemvura, uye kukonzera kusakara kwemidziyo.
Mhinduro:
Isa zvinhu zvinobatsira pakugadzirisa zvinhu zvakaita semafuta emukati/ekunze (semuenzaniso, calcium stearate, polyethylene waxes, kanazvinowedzerwa zvesilicone) pa 0.5-2.0 phr kuderedza viscosity uye kuwedzera kuyerera kwemvura.
Shandisa ma extruder ane huwandu hwakakwira hweL/D kuti uvandudze kusanganisa uye kupararira kwefiller.
Shandisa masisitimu ekukanyira ane simba rekuita kuti simbi isanganiswe zvakaenzana.
Sarudza mafiller ane saizi dzakarongwa uye kurapwa pamusoro kuti uvandudze kuenderana uye kuderedza kukweshana.
2. Kugadzikana kwekupisa
Dambudziko:PVC inogona kuora panguva yekugadzirisa, kunyanya kana paine zvinhu zvakawanda zvinozadza uye zvinodzivisa moto, zvichiburitsa gasi rehydrogen chloride (HCl) izvo zvinotungamira mukuora kwezvinhu, kuchinja ruvara, uye ngura yemidziyo.
Mhinduro:
Wedzera zvinosimbisa kupisa zvakaita secalcium/zinc-based stabilizers pa 2-4 phr kuti HCl isaparare uye kudzivirira kuora.
Shandisa mafuta e soya ane epoxidized (ESO) senzira yekugadzirisa kupisa uye kugadzikana kwemuviri.
Dzora tembiricha dzekugadzirisa zvinhu nemazvo (160-190°C) kudzivirira kupisa zvakanyanya.
Isa ma phenolic antioxidants (semuenzaniso, Bisphenol A pa 0.3-0.5%) kuti uwedzere kuramba kukwegura panguva yekugadzirisa.
3. Kutama kwePlastiki
Dambudziko:Zvishandiso zvepurasitiki zvinoshandiswa kuwedzera kuchinjika zvinogona kufamba-famba pasi pekupisa kwakanyanya (semuenzaniso, munzvimbo dzedata), zvichikonzera kuunganidzwa kwezvisaririra zvinogona kukanganisa kutapurirana kwemasaini kana kuderedza kugara kwenguva refu kwetambo.
Mhinduro:
Shandisa mapurasitiki epolymeric asingafambi panzvimbo pea monomeric (semuenzaniso, DOP, DINP) kuderedza kufamba.
Gadzirai mafomura e "no-liquid" plenum, sezvakatangwa neOTECH, kudzivirira kufamba kwepurasitiki munzvimbo dzinopisa zvakanyanya.
Sarudza mapurasitiki akaita seTOTM, ayo asina kusimba zvakanyanya uye akakodzera kushandiswa pakupisa kwakanyanya.
4. Kuenzanisa Kusashanda Kwemoto Uye Kuderedza Utsi
Dambudziko:Kuwedzera kunonoka kwemurazvo wemoto kuburikidza nezvinhu zvinowedzerwa zvakaita se antimony trioxide (3-5%) kana brominated compounds (12-15%) kunogona kuwedzera kuburitswa kweutsi, zvichiita kuti zvive zvakaoma kuenzanisa zvinhu zvese zviri zviviri. Saizvozvowo, zvinozadza zvakaita se calcium carbonate zvinogona kuderedza utsi asi zvinogona kuderedza oxygen index, zvichikanganisa kunonoka kwemurazvo wemoto.
Mhinduro:
Shandisa musanganiswa unoshanda pamwe chete unodzivirira moto (semuenzaniso, ATH ine zinc borate) kuti ugadzirise kunonoka kwemoto uye kudzvinyirira utsi. Semuenzaniso, ATH inoburitsa utsi hwemvura kuti huvhiringidze kupisa uye hugadzire chigadziko chekudzivirira, icho chinoderedza utsi.
Deredza huwandu hweCaCO₃ huri pakati pe20-40 phr kuti pave nechiyero pakati pemutengo, kudzvinyirirwa kweutsi, uye kunonoka kwemurazvo, sezvo huwandu hwakawanda hunogona kuderedza chiyero cheokisijeni.
Ongorora maformula ePVC anogona kusanganiswa, akadai sePVC ine radiation, kuti uwedzere kunonoka kwemoto usingashandise zvakanyanya halogenated additives.
5. Kugadziriswa uye Hunhu hwepamusoro
Dambudziko:Kuzadza kwakawanda uye kuwedzera kwechinhu kunogona kukonzera kusakwana kwepamusoro, madonhwe emvura, uye kubuda kwechinhu kusingaenderane, izvo zvinokanganisa chitarisiko uye mashandiro echinhu chekupedzisira chetambo.
Mhinduro:ShandisaUpfu hwesilicone hweSILIKE LYSI-100AIzvichinowedzera chakagadzirwa nesiliconeinoshandiswa zvakanyanya sechinowedzera kushanda zvakanaka kwemafutayemasisitimu eresin anoenderana nePVC ekuvandudza hunhu hwekugadzirisa uye kunaka kwenzvimbo. Zvakadai sekugona kuyerera kweresin zviri nani, kuzadza & kusunungura mold, torque shoma yeextruder, uye coefficient yakaderera yekukweshana, greater mar, uye abrasion resistance…
1) Waya dzePVC dzine utsi hushoma uye tambo dzinosanganiswa: kuburitsa kwakasimba, kudzvanywa kushoma, tambo netambo zvakapfava.
2) Waya netambo yePVC yekukweshana kwakaderera: Kukweshana kwakaderera, kunzwa kwakapfava kwenguva refu.
3) Chigadzirwa chePVC chisingakwenyike: Chinodzivirira kukwenyiwa, sezvakaita muma shutter ePVC.
4) Maprofayiri ePVC: zviri nani kuzadza mold uye kuburitsa mold, hapana mold flash.
5) Pombi yePVC: kukurumidza kuburitsa mvura nekukurumidza, COF yakaderera, kutsvedzerera kwepamusoro kwakavandudzika, uye kuchengetedza mari.
Kana uri kusangana nematambudziko ekugadzirisa PVC compound uye zvikanganiso zvepanzvimbo, kana kuti uri kunetseka nekushandisa waya netambo zvePVC zvisingapfuuri utsi, edzaLYSI-100A Silicone Powder inobatsira pakubvisa tsvina zviri nyore uye kushanda zvakanaka.
