Polyvinyl chloride (PVC) ipolymer inogadzirwa ne polymerization ye vinyl chloride monomer (VCM) pamberi pezvinhu zvinotanga zvakaita se peroxides ne azo compounds kana ne mechanism ye free radical polymerization pasi pekushanda kwechiedza kana kupisa. PVC ipolymer material inoshandisa chlorine atomu kutsiva hydrogen atomu mu polyethylene, uye vinyl chloride homopolymers uye vinyl chloride copolymers pamwe chete zvinonzi vinyl chloride resins.
Maketani emamorekuru ePVC ane maatomu echlorine ane simba guru pakati pemamorekuru, izvo zvinoita kuti zvigadzirwa zvePVC zvive zvakasimba, zvakaoma, uye zvine simba remoto, uye zvine simba remoto (rinodzivirira moto zvinoreva hunhu hwechinhu kana kuti chinhu chine mushure mekurapwa kuti chinonotse kupararira kwemoto); zvisinei, mavalue ayo e dielectric constant uye dielectric loss angle tangent akakura kupfuura ePE.
PVC resin ine huwandu hushoma hwemabond maviri, macheni ane matavi uye maresidues ekutanga anosara mu polymerization reaction, pamwe chete nemaatomu e chlorine ne hydrogen ari pakati pemaatomu maviri e carbon ari pedyo, ayo anobviswa chlorine zviri nyore, zvichikonzera kuti PVC iite degradation reaction iri nyore pasi pechiedza nekupisa. Nokudaro, zvigadzirwa zvePVC zvinoda kuwedzera heat stabilizers, dzakadai se calcium-zinc heat stabilizer, barium-zinc heat stabilizer, lead salt heat stabilizer, organic tin stabilizer, nezvimwewo.
Zvishandiso zvikuru
PVC inouya nenzira dzakasiyana uye inogona kugadziriswa nenzira dzakasiyana-siyana, kusanganisira kudzvanya, kuburitsa, kubaya jekiseni, uye kuputira. Mapurasitiki ePVC anoshandiswa zvakanyanya mukugadzira mafirimu, dehwe rekugadzira, kudzivirira kupisa kwewaya netambo, zvigadzirwa zvakasimba, pasi, fenicha, midziyo yemitambo, nezvimwewo.
Zvigadzirwa zvePVC zvinowanzoiswa muzvikamu zvitatu: zvakasimba, zvishoma uye zvakapfava. Zvigadzirwa zvakasimba uye zvishoma zvinogadziriswa zvisina kana kuti zvine purasitiki shoma, nepo zvigadzirwa zvakapfava zvichigadziriswa nehuwandu hwakawanda hwepurasitiki. Mushure mekuwedzera mapurasitiki, tembiricha yekuchinja kwegirazi inogona kudzikiswa, izvo zvinoita kuti zvive nyore kugadzirisa patembiricha yakaderera uye zvinowedzera kuchinjika uye purasitiki yeketani yemamorekuru, uye zvinoita kuti zvikwanisike kugadzira zvigadzirwa zvakapfava zvinochinjika patembiricha yemumba.
1. Mapurofayiri ePVC
Inonyanya kushandiswa kugadzira magonhi nemahwindo nezvinhu zvinochengetedza simba.
2. Mapaipi ePVC
Mapaipi ePVC ane mhando dzakasiyana-siyana, mashandiro akanaka kwazvo uye mashandisirwo akasiyana-siyana, uye ane chinzvimbo chakakosha pamusika.
3. Mafirimu ePVC
PVC inogona kugadzirwa kuita firimu rinopenya kana rine ruvara rine ukobvu hwakatarwa uchishandisa karenda, uye firimu rinogadzirwa nenzira iyi rinonzi firimu rakarongwa. Zvinhu zvePVC zvinogonawo kuputirwa kuita firimu uchishandisa michina yekuumba, uye firimu rinogadzirwa nenzira iyi rinonzi firimu rekuumba. Firimu rinogona kushandiswa pazvinangwa zvakawanda uye rinogona kugadzirwa kuita mabhegi, majasi emvura, machira etafura, maketeni, matoyi anofefeterwa, nezvimwewo nenzira yekucheka nekuvhara kupisa. Mafirimu akafara anopenya anogona kushandiswa kuvaka magreenhouse nemagreenhouse epurasitiki, kana kushandiswa semafirimu epasi.
4. Bhodhi rePVC
Zvinowedzerwa nechinosimbisa, mafuta ekuisa muchina uye chizoro, uye mushure mekusanganisa, PVC inogona kuburitswa mumapaipi akasiyana-siyana akaomarara, mapaipi akaumbwa uye mapaipi akakombama nechinhu chinoburitsa mvura, uye inoshandiswa sepaipi yekudonhera pasi, mapaipi emvura yekunwa, waya yemagetsi kana manera ekubata masitepisi. Mapepa akarembera anopindirana uye anodzvanywa nekupisa kuti agadzire mapepa akaomarara ane ukobvu hwakasiyana-siyana. Mapepa anogona kuchekwa kuita maumbirwo anodiwa uye ozobatanidzwa nemhepo inopisa uchishandisa PVC welding rods mumatangi akasiyana-siyana ekuchengetedza asingashandise makemikari, ducts nemagaba, nezvimwewo.
5. Zvigadzirwa zvePVC zvakapfava
Uchishandisa extruder, inogona kuburitswa mumahosipaipi, tambo, waya, nezvimwewo; uchishandisa muchina wekuumba majekiseni une mhando dzakasiyana-siyana, inogona kugadzirwa kuita masandle epurasitiki, shangu, masilipa, matoyi, zvikamu zvemota, nezvimwewo.
6. Zvinhu zvekurongedza zvePVC
Zvigadzirwa zvePVC zvekurongedza zvinonyanya kugadzirwa mumidziyo yakasiyana-siyana, firimu nepepa rakaoma. Mamidziyo ePVC anonyanya kugadzirwa mumvura ine zvicherwa, zvinwiwa, mabhodhoro ezvizoro, asiwo ekurongedza mafuta akacheneswa.
7. Siding neflooring zvePVC
PVC siding inonyanya kushandiswa kutsiva aruminiyamu siding, PVC floor tiles, kunze kwechikamu chePVC resin, zvimwe zvikamu zvacho zvinhu zvakadzokororwa, manamati, fillers nezvimwe zvikamu, zvinonyanya kushandiswa munhandare yendege uye kune dzimwe nzvimbo dzakaoma pasi.
8. Zvigadzirwa zvevatengi zvePVC
Zvigadzirwa zvePVC zvinowanikwa kwese kwese muhupenyu hwedu hwezuva nezuva. PVC inoshandiswa kugadzira matehwe akasiyana-siyana ekugadzira mabhegi ekutakura zvinhu, zvigadzirwa zvemitambo zvakaita sebasketball, mabhora enhabvu uye mabhora erugby. Inoshandiswawo kugadzira yunifomu uye mabhandi emidziyo yekudzivirira. Machira ePVC ezvipfeko anowanzo kuve machira anonyudza (hapana chifukidziro chinodiwa) akadai semaponcho, mabhurugwa evana, majaketi eganda ekugadzira uye mabhutsu emvura akasiyana-siyana. PVC inoshandiswawo muzvigadzirwa zvakawanda zvemitambo nezvevaraidzo zvakaita sematoyi, marekodhi nezvinhu zvemitambo.
