Isticmaal

1. Warshadaha dhismaha:Sida wakiilka biyaha-haynta iyo dib-u-dejiyaha hoobiye sibidhka, waxay ka dhigaysaa hoobiye mid la soo saari karo.Loo isticmaalo sida wax-ku-xidhaha ee koollada, gypsum-ka, budada-buuska ah ama qalabka kale ee dhismaha si loo hagaajiyo faafitaanka loona dheereeyo wakhtiga hawlgalka.Waxaa loo isticmaalaa sidii dhejis loogu talagalay dhoobada dhoobada, marmar, qurxinta caaga ah, sida kor u qaadida koollada, waxayna sidoo kale yareyn kartaa qadarka sibidhka.Haysashada biyaha ee HPMC waxay ka ilaalin kartaa slurry-ku inuu dillaaco sababtoo ah si degdeg ah u engejiya codsiga ka dib, iyo kor u qaadida xoogga ka dib qallafsanaanta.
2. Wax-soo-saarka dhoobada:si ballaaran loo isticmaalo sida binder ee soo saarista alaabta dhoobada.
3. Warshadaha dahaarka:Sida dhumuc weyn, kala firdhisan iyo xasiliye ee warshadaha daahan, waxa ay leedahay waafaqsan wanaagsan ee biyaha ama dareerayaasha organic.sida rinji-saar.
4. Daabacaadda qalin:sida dhumuc weyn, kala firdhisan iyo xasiliye ee warshadaha khad, waxay leedahay waafaqid wanaagsan ee biyaha ama dareerayaasha organic.
5. Caag:loo isticmaalo sida wakiilka sii daynta wax ka beddelidda, jilcisa, saliidaha, iwm.
6. Polyvinyl chloride:Waxaa loo isticmaalaa sida kala firdhiso soo saarista chloride polyvinyl, waana wakiilka ugu muhiimsan ee diyaarinta PVC by polymerization hakinta.
7. Warshadaha dawooyinka:alaabta daahan;alaabta filimka;Qalabka polymer-ka ee lagu xakameynayo heerka-is-diyaarinta sii-deynta joogtada ah;xasiliyayaal;wakiilada shaqada ka joojinaya;xirmooyinka kiniinka;dharbaaxayaal
8. Kuwo kale:Waxa kale oo si weyn loogu isticmaalaa hargaha, warshadaha wax soo saarka waraaqaha, ilaalinta khudradda iyo khudaarta iyo warshadaha dunta.
