Isicelo sePVC S-1300
isicelo sePVC S-1300,
I-PVC 1300 yebhodi eguquguqukayo ecacileyo, I-PVC S-1300 yentambo, I-PVC S-1300 yefilimu,
I-Polyvinyl chloride (i-PVC) i-resin yi-polymer ephezulu eveliswa yi-polymerization ye-ethylene.Ukumiswa kwepolymerization kusetyenziswa njengendlela eqhelekileyo yokwenziwa kwepolymerization kwishishini.Idla ngokuba sisiqina esinokuthanjiswa ngokufudumeza.Xa ishushu, ngokuqhelekileyo inomlinganiselo weqondo lokushisa lokunyibilika okanye ukuthambisa, kwaye unokuba kwimeko yokuhamba kweplastiki phantsi kwesenzo samandla angaphandle.Umzi-mveliso unokongeza iplastiki okanye ezinye izinto ezincedisayo ukuhlangabezana neemfuno zokuvelisa ngokweemfuno zokusebenza kweemveliso zeplastiki.
IBanga S-1300 lisetyenziswa ikakhulu ukuvelisa iimveliso eziguquguqukayo eziphezulu, izixhobo ezicinezelweyo, ukubumba okuqinileyo kunye nokuguquguqukayo kwe-extrusion kunye nezixhobo zokugquma, njl. njengefilimu ebhityileyo, ipleyiti ebhityileyo, isikhumba sokwenziwa, ucingo, i-cable sheath kwaye ithambile zonke iintlobo zeeprofayili.

Isicelo
Isicelo kwizinto zentambo.I-molecular weight distribution of PVC resin iyadingeka ukuba ifaneleke ngakumbi kwiimfuno zeentambo eziphezulu.Iimpawu zemishini yezinto zekhebula eziveliswa yi-S-1300 zingcono.Nangona amandla e-dielectric e-S-1300 ephantsi kancinci, isenkulu kuneemfuno zesalathiso sezinto ze-cable zokugquma.Ngoko ayiyi kuchaphazela ukusetyenziswa kwayo kwizinto zokukhusela.
Isicelo kwibhodi ebhetyebhetye ecacileyo.Kukho iintlobo ngeentlobo zeebhodi ezithambileyo zePVC kwimarike, njengeekhethini zocango, amalaphu etafile, imicu yemvula yeengcango zemoto kunye neefestile, njl. amanqaku ambalwa ekristale.Ukuhanjiswa kokukhanya, inkungu kunye nesalathiso esimthubi sebhodi ye-S-1300 ebonakalayo eguquguqukayo ingcono kunesalathiso seshishini, kwaye ineempawu ezingcono zoomatshini.
Ukusetyenziswa kwiifilimu ezincinci.Iimveliso zefilimu ye-PVC zinokwahlulwa zibe yifilimu yezolimo, ifilimu enekhalenda kunye nefilimu eshwabeneyo nobushushu.Phakathi kwazo, ifilimu encitshiswayo ubushushu iveliswa ikakhulu nge-S-1300 uhlobo lwe-PVC, ngelixa ifilimu yezolimo kunye nefilimu yekhalenda iveliswa kakhulu nge-S-1300 PVC resin.Ifilimu ye-calendered eyenziwe nge-S-1300 kunye ne-Plasitiki ye-DOP ineempawu zamandla aphezulu omatshini, ukuqina okulungileyo, ukuxhathisa kwe-alkali kunye nokuchasana nokuvezwa, ngoko ubomi bayo benkonzo bungaphezu kweminyaka eyi-3.
