Waalka cagta ee PVC
Waalka hoose ee PVC waa nooc ka mid ah waalka tamarta-badbaadinta, kaas oo guud ahaan lagu rakibay dhamaadka hoose ee tuubada biyaha hoostooda ee bamka biyaha si loo xaddido dareeraha ku jira tuubada biyaha inuu ku soo laabto isha biyaha, isagoo ciyaaraya shaqada kaliya galaya laakiin aan ka bixin.Waxaa jira meelo badan oo biyo gelin ah iyo feeraha xoojinta ee daboolka waalka, kuwaas oo aan fududayn in la xannibo.Waalka hoose ayaa miisaankiisu yar yahay waana sahlan tahay in la rakibo.
Hababka isku xirka waa: nooca isku-xidhka, iyo qaab-dhismeedka alaabadu waa: nooca kubbadda sabaynaysa. Waxaa loo isticmaali karaa bambooyin kala duwan oo centrifugal ah iyo bambooyin iskood isku toosiya.
Alaabtu waxay leedahay qaab-dhismeed cusub iyo waxqabadka xidhidhiyaha sare.Waxay iska caabin kartaa aashitada, alkali iyo daxalka. Waqti dheer la isticmaalo.Waxaa si weyn loogu isticmaalaa warshadaha kiimikada, fiber kiimikaad, chlor-alkali, awoodda korontada, farmashiyaha, sunta cayayaanka, dheeha, dhalaalid, cuntada, daaweynta bulaacada, mariculture, iyo warshadaha kale.
PVC waa budo cad oo leh qaab-dhismeedka amorphous.Heerka branching waa yar yahay, cufnaanta qaraabo ku saabsan tahay 1.4, heerkulka kala guurka galaas waa 77 ~ 90 ℃, oo wuxuu bilaabaa inuu qudhmi at qiyaastii 170 ℃.Waxay leedahay xasillooni liidata iftiinka iyo kuleylka, ka sarreeya 100 ℃ ama waqti dheer ka dib.Soo-gaadhista iftiinka qorraxdu waxay u jajabi doontaa si ay u soo saarto hydrogen chloride, taas oo si dheeraad ah u hagaajin doonta burburka, taasoo keenaysa midab, iyo sifooyinka jireed iyo farsamada sidoo kale si degdeg ah ayey hoos u dhici doonaan.Codsiyada wax ku oolka ah, xasiliyayaasha waa in lagu daraa si loo hagaajiyo kuleylka iyo xasilloonida iftiinka.
Astaamaha
Qalab:Pvc
1) Caafimaad qaba, dhexdhexaad ah bakteeriyada, oo waafaqsan heerarka biyaha la cabbo
2) U adkaysta heerkulka sare, xoog saameyn wanaagsan leh
3) Rakibaadda ku habboon oo la isku halayn karo, kharashyada dhismaha oo hooseeya
4) Hantida kulaylka-xakamaynta heer sare ah oo ka imanaya dhaqdhaqaaqa kulaylka ugu yar
5) Fudud, ku habboon in la qaado oo la qabto, u fiican badbaadinta shaqada
6) Darbiyada gudaha ee siman waxay yareeyaan luminta cadaadiska waxayna kordhiyaan xawaaraha socodka
7) Dahaarka dhawaaqa (waxaa yareeyay 40% marka loo eego tuubooyinka birta galvanized)
8) Midabada iftiinka iyo naqshadeynta aadka u fiican waxay xaqiijiyaan ku habboonaanta rakibaadda qarsoon iyo kuwa qarsoon labadaba
9) Dib loo warshadayn karo, deegaan-u-saaxiibtinimo, waafaqsan heerarka GBM
10) Nolosha isticmaalka aad u dheer ugu yaraan 50 sano
