Codsiyada ugu muhiimsan:
Xabagta PVC waxaa lagu farsameeyaa noocyo kala duwan oo baco ah, sida ku cad isticmaalkeeda waxaa loo qaybin karaa laba qaybood oo ah alaab jilicsan oo adag, inta badan loo isticmaalo soo saarista qaybo hufan, tuubooyinka tuubooyinka, kaararka dahabka, qalabka dhiig-shubidda, jilicsan iyo adag. tuubooyinka, taarikada, albaabada iyo daaqadaha, profiles, filimada, qalabka dahaarka korontada, galka fiilada, walxaha dhiigga lagu shubo, iwm.
1.PVC guud ahaan jilicsan iyo alaab adag - iyadoo la isticmaalayo extruder waxaa lagu tuujin karaa tuubooyinka jilicsan iyo kuwa adag, fiilooyinka, fiilooyinka, iwm.;Mashiinka qaabaynta duritaanka iyo caaryada kala duwan, waxaa laga samayn karaa kabo caag ah, lugaha, dacas, alaabta carruurtu ku ciyaarto, waxyaabaha maalinlaha ah loo baahan yahay iyo baabuurta iyo qalabka korontada.
2 PVC tuubo adag iyo profile - marka loo eego caagadaha kale, PVC caabbinta gabowga waa mid aad u fiican, xoogga saameynta sare iyo adkaanta, qiimo jaban, oo ku habboon tuubooyinka dheecaanka iyo tuubooyinka kale ee dhismaha, iyo profile profile.
3 Filimka PVC - PVC iyo waxyaabaha lagu daro isku dhafan, balaastiigga, isticmaalka saddex ama afar qaab duuban oo duuban oo dhumucdiisuna tahay filim hufan ama midab leh, oo leh habkan habka filimka, waxay noqdaan filim caleenta.Sidoo kale waa la gooyn karaa, bacaha baakadaha kuleyliyaha, jaakadaha roobka, dharka miiska, daahyada, alaabta lagu ciyaaro ee la buufiyo iyo wixii la mid ah.Filim hufan oo ballaadhan ayaa loo isticmaali karaa aqalka dhirta lagu koriyo, aqalka dhirta lagu koriyo ee caagga ah iyo filim caag ah.Ka dib fidinta labada jiho ee filimka, hantida kuleylka kulaylka, ayaa loo isticmaali karaa baakadaha la yareeyo.
4 badeecooyinka dahaarka leh ee PVC - oo leh substrate maqaar macmal ah ayaa PVC ku wareersan maro ama warqad, ka dibna 100 darajo Celsius oo ka sarreeya caag ah.Waxa kale oo ay noqon kartaa PVC iyo filimka calending kaaliyaha ah, ka dibna wada riixaya substrate ah.Maqaarka macmalka ah ee aan lahayn substrate si toos ah ayaa mashiinka calending u dhejiyaa dhumuc gaar ah oo xaashi jilicsan, ka dibna lagu cadaadiyo qaabka.Maqaar macmal ah ayaa loo isticmaali karaa in lagu sameeyo shandad, bacaha, daboolka buugaagta, fadhiga fadhiga iyo barkimada baabuurta, iyo maqaar sagxadda, oo loo isticmaalo sida qalabka dhismaha.
5.PVC alaabada xumbo - isku dhafka PVC ee jilicsan, ku dar qadarka saxda ah ee wakiilka xumbo si aad u sameyso walxaha xaashida, dhejinta xumbo balaastigga, kabaha xumbo, kabaha, kabaha, iyo alaabta baakadaha baakadaha aan shoogga lahayn.Waxa kale oo aad u isticmaali kartaa FOUNDATION extruder xaashida PVC ee adag xumbo hoosaysa, waxay bedeli kartaa tijaabada alwaax, waa nooc cusub oo qalabka dhismaha ah.
6 xaashida hufan ee PVC - PVC waxay ku dartaa wax ka beddelka saamaynta iyo xasiliyaha, ka dib marka la isku daro, balaastiig, calending oo noqo xaashi hufan.Isticmaalka samaynta kulul waxaa laga samayn karaa weelal hufan oo dhuuban ama loo isticmaali karaa baakadaha finan vacuum ah, waa alaabta baakadaha fiican iyo alaabta qurxinta.
7 saxan adag oo PVC ah iyo saxan - xasiliyaha PVC, saliidaha iyo buuxinta, ka dib marka la isku daro, oo leh extruder waxaa lagu faafin karaa caliber kala duwan oo ah tuubo adag, tuubo qaabaysan oo gaar ah, gogosha, loo isticmaalo sida tuubada hoose, tuubada cabitaanka, gacmaha siliga ama jaranjarada gacanta.Isku darka kululaynta xaashida caleenta ah waxay samayn kartaa go'yaal adag oo dhumucyo kala duwan leh.Saxanka waa la gooyn karaa qaabka la rabo, ka dibna isticmaalka qalabka PVC ee leh alxanka hawada kulul ee noocyo kala duwan oo kiimiko ah oo u adkaysta taangiyada kaydinta, dhuumaha hawada iyo weelasha.
8.PVC kale - albaabada iyo Daaqadaha ayaa laga sameeyay qalab adag oo qaabaysan.Waddamada qaarkood waxay lahaayeen albaabbada alwaax iyo daaqadaha aluminiumka iyo albaabada kale ee caadiga ah iyo suuqa daaqadaha;Qalabka alwaax ku dayashada ah, qalabka dhismaha birta ee jiilka (waqooyi, dhinaca badda);Weel madhan.
