PVA
Jumlada PVA Polyvinyl Khamriga
dulmar alaabta
Aalkolada Polyvinyl (PVA) waa polymer-ka biyaha ku milma oo inta badan ku cad cad lallabbo, flocculent, ama qaab budo ah.
Marka labaad, sifooyinka alaabta
Biyo nadiif ah oo heer sare ah: waxay ku milmi kartaa biyaha heerkul kala duwan si loo sameeyo xal hufan.
Ku dheggan wanaagsan: waxay saameyn xooggan ku leedahay isku xirnaanta agabyada kala duwan.
Sameynta filim heer sare ah: Filimka la sameeyay wuxuu leeyahay awood sare iyo dabacsanaan.
Iska caabinta dareeraha: Ilaa xad, waxay iska caabin kartaa nabaad-guurka dareerayaasha caadiga ah.
Biocompatibility: Marka la eego aan sun ahayn oo saaxiibtinimo u leh jidhka bini'aadamka iyo deegaanka.
isticmaalka alaabta
Warshadaha dharka
Loo isticmaalo sida walaxda lagu cabbirayo si loo hagaajiyo xoogga loona xidho iska caabinta dunta.
Kaaliyeyaasha daabacaadda iyo midabaynta, waxay caawiyaan ku-dhejinta dheeha iyo qaybinta lebbiska.
Warshadaha waraaqaha
Wakiilka cabbiraadda dusha warqad si loo kordhiyo xoogga iyo caabbinta biyaha ee warqadda.
Xabagta dahaarka midabaynta si loo hagaajiyo sifooyinka waraaqaha dahaarka leh.
Beer xabagta
Xabagta alwaax, warqad, fiber iyo walxo kale.
Warshadaha dhismaha
Waxyaabaha lagu daro sibidhka si loo hagaajiyo sifooyinka sibidhka.
Goobta caafimaadka
Walxaha ceeriin ee kaabsulka daawada, walxaha caawiya ee daawada indhaha.
Habka wax soo saarka
Guud ahaan waxaa diyaariya alkolysis of polyvinyl acetate.
Rajada suuqa
Iyada oo ay sii kordheyso baahida loo qabo agabka waxqabadka sare leh ee warshadaha kala duwan, rajada suuqa ee PVA waa mid ballaaran. Iyada oo ay ku kacday cusboonaysiinta warshadaha soo jireenka ah sida dunta iyo waraaqaha, iyo sidoo kale horumarinta beeraha soo baxaya sida biomedicine iyo qalabka elektaroonigga ah, baahida suuqa ayaa la filayaa in ay sii socoto.
isticmaal taxaddar
Ka fogow qoyaanka iyo heerkulka sare marka aad kaydinayso.
Marka la kala diro, heerkulka iyo xawaaraha wax-karinta waa in la xakameeyaa si loo hubiyo kala diris ku filan iyo waxqabadka aan la taaban.
Dooro moodooyinka ku habboon iyo qeexitaannada iyadoo loo eegayo shuruudaha codsi ee kala duwan.
Tusaale ahaan, warshadaha dharka, PVA oo leh viscosity gaar ah iyo shahaadada alkolysis waxay u baahan tahay in lagu doorto iyada oo loo eegayo shuruudaha alaabta iyo habka dhogorta; Codsiga xabagta, qaabeynta iyo isticmaalka PVA waa in lagu hagaajiyaa si waafaqsan dabeecadda koollada.
Si loo soo koobo, khamriga Polyvinyl wuxuu door muhiim ah ka ciyaaraa meelo badan oo leh hantidiisa gaarka ah, isagoo siinaya taageero xooggan horumarinta warshadaha la xidhiidha.
