galoofyada PVCwaa galoofyada khafiifka ah ee la sameeyay iyada oo la isku qasay xabagta koolada polyvinyl chloride, balaastiiste, xasiliye iyo wakiilka yareeya viscosity-ga oo la geliyo resin caag 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, 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.
Sifooyinka: 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, crystals dareeraha 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, cuncun maqaarka lahayn, ifafaale xasaasiyad.4. Jiilka boodhka hooseeya iyo content ionic, baakad boodh-vacuum ah.5. Lagu dabaqi karo qolka nadiifka ah / qolka nadiifka ah / aqoon isweydaarsiga nadiifinta / semiconductor, wax soo saarka disk adag, optics sax ah, elektiroonigga indhaha, wax soo saarka dareeraha LCD / DVD, daawada noolaha, qalabka saxda ah, daabacaadda PCB 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, rinjiga iyo warshadaha daahan, warshadaha daabacaadda iyo rinjiyeynta, beeraha, kaymaha, xanaanada xoolaha iyo warshadaha kale.

Buuxiyaha qadar ku filan
Ku dar dhammaan noocyada alaabta ceeriin ee qiyaasta, hal mar walaaq si aad xumbo-jariso oo ha istaagto, shaandhayso, walaaq laba jeer oo faakiyuum xumbo.
Habka wax soo saarka galoofyada PVC
Ka dib shaandhaynta, faakuyumaynta iyo istaagida, isku dar ah ayaa lagu shubaa haanta impregnation ee khadka wax soo saarka.Under xaaladaha wax soo saarka caadiga ah, caaryada gacanta on line si toos ah galaan taangiga impregnation ah, iyo caaryada gacanta ee emulsion ku lifaaqan ka soo baxa taangiga impregnation markeeda, wareegaya si joogto ah inta lagu guda jiro March si ay u sameeyaan emulsion ah dusha sare ee caaryada gacanta lebis. , oo ka dhig emulsion-ka xad-dhaafka ah inuu hoos u tifqxo.Dareeraha qulqulaya waxaa lagu soo celiyaa haanta impregnation iyada oo loo marayo haanta ururinta.Ka dib marka la daadiyo 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 lagu 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.galoofyada PVC 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-samaynta joogtada ah → dhejinta → dareere → dubista → qaboojin → bishimaha duubista → budada rida (daqiiqda hadhuudhka)
Socodka socodka galoofyada PVC ee aan budada lahayn
Isku qas → Walaaqin → Shaandhayn → Joogsi iyo Xumbo-saarid → Waxyaabo dhegdheg → Duubista → Dubidda → Qaboojinta → Daaweynta biyaha PU
