Kodi mitundu ya polimature polima?

Kubwezeretsa ma pollmer inlymer (RPP) kumapezeka m'mitundu yosiyanasiyana, iliyonse imagwirizana ndi zomwe mukufuna kuchita komanso zomwe zikuchitika. Kuphatikizidwa, katundu, kugwiritsa ntchito rups amatha kusiyanasiyana malinga ndi mitundu monga mtundu wa polimer, zowonjezera zamankhwala, ndikupanga njira. Nazi mitundu yofananira yobwezeretsedwa ndi ma polimate:

1. Mtundu wa Polymer:
   • Ethylene-vinyl acetate (Eva) RPPP: Rups yochokera ku Eva ndi yosiyanasiyana ndipo imagwiritsidwa ntchito kwambiri popanga ma tayi, matope, komanso zodzikongoletsera. Amapereka kusinthasintha bwino, kotsatira, ndi kukana madzi.
   • VIYYL Acetate-Ethylene (VAE) RPP: RAPS yochokera ku RAPS ikufanana ndi Eva RPPS koma ingapatse madzi osinthika ndi kulimba. Ndioyenera kugwiritsa ntchito ntchito monga zomatira tile, membrane wosinthika, ndi zigawo zosindikiza.
   • Acrylic RPPP: RPHPS-zochokera ku Acrylic imapereka zomata zabwino kwambiri, kukana nyengo, ndi kulimba. Nthawi zambiri amagwiritsidwa ntchito kunja komanso kumaliza ma systems (mabodza), zokumba zosafunikira, ndi matope ogwiritsa ntchito kwambiri.
   • Styrene-acrylic RPPP: Ruryrene-phompho-ma acrylic-ruclic amapereka mogwirizana, kusinthasintha, ndi kukana madzi. Ndioyenera kugwiritsa ntchito ntchito monga mafuta opondera, osokoneza bongo, ndi zokutira.
   • Molyvinyl mowa (pva) RPPP: RPPS yolemba mafayilo imapereka kusinthasintha kwakukulu, kagwiritsidwe ka kamafilimu, komanso kukana alkalis. Amagwiritsidwa ntchito pogona mkati, zowoneka bwino, komanso zokongoletsera.
2. Zowonjezera Zothandiza:
   • Mapulasitiki: RPPS ina ikhoza kukhala ndi mafayilo osintha, kugwirira ntchito, komanso kutsatira. RPPS yopukusira pulasitiki nthawi zambiri imagwiritsidwa ntchito mu membrane yopanda madzi mosasinthika, zimbudzi, komanso mafilimu osokoneza bongo.
   • Okhazikika: Okhazikika amawonjezeredwa ku Ripp Kumalimbikitsa moyo wa alumali, kusunthika, ndi kuperekerapo. Amathandizira kupewa kuphatikizika ndikuwonetsetsa kuti kupezeka kwa rupp yambiri m'madzi.
3. Kukula kwa tinthu ndi morphology:
   • RPPS imapezeka mu tinthu tating'onoting'ono tating'ono ndi morphologis kuti tikwaniritse zofunika pa ntchito. Zigawo zabwino zimatha kupereka mapangidwe a makanema abwino komanso osalala kwambiri, pomwe tinthu tating'onoting'ono tingathe kupititsa patsogolo madzi osungira komanso makina.
4. Maphunziro a Sukulu:
   • Opanga ena amapereka magiredi apadera a RPPS zogwirizana ndi mapulogalamu kapena magwiridwe antchito. Izi zitha kuphatikizira mphesa ndi kukana madzi owonjezera, kukhazikika kwaulere, kapena kuwongolera katundu.
5. Mapangidwe Amtundu:
   • Kuphatikiza pa mitundu yonse, mapangidwe a ngwazi amatha kupangidwa kuti akwaniritse zofunikira zapadera za makasitomala kapena ntchito zawo. RPPS yamitundu imatha kuphatikiza ma polima, owonjezera, kapena osinthira magwiridwe antchito potengera makasitomala.

Mitundu yamitundu yosiyanasiyana yopezeka pamsika imawonetsa zofunikira zosiyanasiyana monga zojambula, zomata, pomwe ma RPPS amatenga gawo lofunikira pakulimbikitsa magwiridwe antchito, kukhazikika, komanso magwiridwe antchito.
