galoofyada PVCwaa galoofyo dhuuban oo la sameeyay iyada oo la isku qasayo xabagta koolada polyvinyl chloride, balaastiiste, xasiliye iyo wakiilka yareeya viscosity galay xabagta caaga ah, kaas oo la miiray, la qalajiyey oo balaastig lagu shubay habka.
Tilmaamaha galoofyada PVC
galoofyada PVCwaxay ka samaysan yihiin chloride polyvinyl iyada oo loo marayo hab gaar ah.Gacan-gashiyadu waa kuwo aan xasaasiyad lahayn, budo-free, jiil yar oo boodh ah, maaddo ionic ah oo hooseeya, oo ka madax bannaan balaastikada, esters, saliidda silikoon iyo qaybaha kale, oo leh caabbinta kiimikada xooggan, dabacsanaan iyo taabasho wanaagsan, fudud oo raaxo leh in la xidho, oo leh anti- guryaha taagan, waxaana loo isticmaali karaa deegaan aan boodh lahayn.
Astaamaha: 1. U adkaysta asiidhyada daciifka ah iyo alkalis;2. Waxyaalaha ionic oo hooseeya;3. Dabacsanaan iyo taabasho wanaagsan;4. Ku haboon hababka wax soo saarka sida semiconductors, kiristaalo dareere ah iyo saxannada adag.
galoofyada PVC waxay isticmaalaan kala duwanaansho
1, wax PVC tayo sare leh.2. Isticmaalka guud ee labada gacmood, curcurka cidhifka duuban.3. Habka daaweynta ka dib gaar ah, ma cuncun maqaarka, ifafaale xasaasiyad.4. Jiilka boodhka hooseeya iyo content ionic, baakad aan boodh lahayn.5. Lagu dabaqi karo qolka nadiifka ah / qolka nadiifka ah / aqoon isweydaarsiga sifaynta / semiconductor, wax soo saarka disk adag, optics sax ah, elektiroonigga indhaha, LCD/DVD wax soo saarka dareeraha crystal, daawada noolaha, qalabka saxda ah, PCB daabacaadda iyo warshadaha kale.galoofyada PVC ayaa si weyn loogu isticmaalaa ilaalinta shaqada iyo nadaafadda guriga ee kormeerka caafimaadka, warshadaha cuntada, warshadaha kiimikada, warshadaha elektiroonigga ah, warshadaha dawooyinka, warshadaha rinjiga iyo daahan, warshadaha daabacaadda iyo midabaynta, beeraha, kaymaha, xanaanada xoolaha iyo warshadaha kale.

Ku dar dhammaan noocyada alaabta ceeriin, hal mar walaaq si aad xumbo-jariso oo ha istaagto, shaandheeya, walaaq laba jeer oo faakiyuum xumbo.
Habka wax soo saarka galoofyada PVC
Ka dib shaandhaynta, faakuumaynta iyo istaagida, isku dar ah ayaa lagu shubaa haanta impregnation ee khadka wax soo saarka.Xaaladaha wax soo saarka caadiga ah, caaryada gacanta ee khadka ayaa si toos ah u galaya taangiga impregnation, iyo caaryada gacanta oo leh emulsion ayaa ka soo baxa taangiga impregnation markeeda, si joogto ah u wareegaya inta lagu jiro socodka si ay u sameeyaan emulsion ee dusha sare ee caaryada gacanta , oo ka dhig emulsion-ka xad-dhaafka ah hoos u soo tifqado.Dareeraha qulqulaya waxaa lagu soo celiyaa haanta impregnation iyada oo loo marayo haanta ururinta.Ka dib marka ay daadato emulsion-ka xad-dhaafka ah, caaryada gacantu waxay la socotaa xariiqda wax soo saarka foornada, halkaas oo heerkulka foornada lagu xakameynayo 230-250 darajo Celsius iyo emulsion-ka taabashada gacanta ayaa la kariyaa oo la sameeyay xaaladdan.Caaryada gacanta ee foornada si dabiici ah ayaa loo qaboojiyey, dibnaha loo duubaa oo budada loo duubaa, ka dibna galoofyada gacanta ayaa laga saarayaa caaryada gacanta, kuwaas oo si joogto ah ugu socda taangiga impregnation.Gacma-gashiyada PVC-ga ee aan la rarin waa la budo ka dibna waxaa loo kaydiyaa sidii alaab dhammaatay.
Habka galoofyada PVC budada ah
Dawaynta → isku dhafka → shaandhaynta → xumbo-baxa taagan → dhejinta → dareere → dubista → qaboojin → bishimaha duubista → budada rida (burka galleyda) → dumin → budada ka saarida → hubinta tayada
Socodka socodka galoofyada PVC ee aan budada lahayn
Isku qas → Walaaqin → Shaandhayn → Joogsi iyo Xumbo-saarid → Waxyaabo dhegdheg → Dubid → Dubin → Qaboojin → Daaweynta biyaha PU
