Waa maxay hababka dib-u-warshadaynta balaastikada qashinka?
Waxaa jira saddex hab oo dib-u-warshadaynta: 1. Daaweynta Burburka kulaylka: Habkani waa in balaastigga lagu kululeeyo oo la gooyo saliid ama gaas, ama loo isticmaalo tamar ahaan ama dib loo isticmaalo hababka kiimikada si loo kala saaro alaabada petrochemical si loo isticmaalo. Habka dumanka kulaylku waa: polymer-ka ayaa depolymerizes heerkul sare, iyo silsiladaha molecular jejebi oo burburay molecules yar yar iyo monomers. Habka kala-goynta kulaylku wuu ka duwan yahay, badeecada ugu dambeysana way ka duwan tahay, taas oo noqon karta qaab monomer ah, polymer miisaan yar oo kelli ah, ama isku dhafka hydrocarbons badan. Doorashada habka saliidaynta ama gaaska waa in lagu saleeyaa baahiyaha dhabta ah. Hababka loo isticmaalo waa: Nooca taangiga dhalaalidda (ee PE, PP, random PP, PS, PVC, iwm.), Mikrowave nooc (PE, PP, random PP, PS, PVC, iwm), nooca fur (loogu talagalay PE, PP). , PS, PMMA). Nooca uumiga tuubada (ee PS, PMMA), nooca sariiraha ebullating (ee PP, random PP, cross-linked PE, PMMA, PS, PVC, iwm), nooca kala furfuran catalytic (ee PE, PP, PS, PVC, iwm. ). Dhibka ugu weyn ee bacaha kuleyl ahaan u burburiya waa caagadaha oo leh kulaylka kuleylkoodu liito, taas oo ka dhigaysa warshadaynta kulaylka baaxadda weyn iyo dildilaaca kulaylka ay adagtahay in la fuliyo. Marka lagu daro burburka kulaylka, waxaa jira habab kale oo lagu daweeyo kiimikaad, sida dildilaaca kulaylka, hydrolysis, alkolysis, hydrolysis alkaline, iwm, kuwaas oo soo kabsan kara walxo kiimiko ah oo kala duwan.
2. Dib u warshadaynta dhalaalaysa Habkani waa in la kala saaro, la burburiyo, oo la nadiifiyo caagadaha wasakhda ah, ka dibna dhalaalin oo laga dhigo baco. Alaabooyinka qashinka ah iyo alaabta hadhaaga ah ee laga helo dhirta wax-soo-saarka resin-ka iyo warshadaynta bacaha iyo warshadaynta, habkan waxa loo isticmaali karaa in lagu soo saaro alaabooyin kala duwan oo tayo wanaagsan leh. Waa dhib in la kala saaro oo la nadiifiyo caagadaha qashinka ah ee bulshada loo isticmaalo, kharashkuna waa qaali. Guud ahaan waxaa loo isticmaalaa in lagu sameeyo alaab qallafsan iyo kuwa hooseeya. 3. Dib-u-isticmaalka isku dhafan: Habkani waa in la jebiyo qashinka caagagga ah, sida PS xumbada, xumbo PU, iwm oo la jarjaro qaybo cayiman, ka dibna lagu qaso dareerayaasha, xabagta, iwm si loo sameeyo looxyo iyo xargaha khafiifka ah.
