Mapulogalamu Odziwika:

1. Zomatira:

• PVA 2488 nthawi zambiri imagwiritsidwa ntchito ngati chigawo chofunikira pazomatira zosiyanasiyana, kuphatikiza zomatira zamatabwa ndi zomatira zamapepala. Zimapereka mphamvu yolumikizana bwino komanso kusinthasintha.

2. Kukula kwa Nsalu:

• M'makampani opanga nsalu, PVA 2488 itha kugwiritsidwa ntchito popanga masingidwe kuti apititse patsogolo mphamvu ndi kasamalidwe ka ulusi.

3. Zopaka Papepala:

• PVA 2488 itha kugwiritsidwa ntchito pamakampani opanga mapepala kuti azikutira, kukulitsa mawonekedwe apamwamba komanso kusindikizidwa kwa pepala.

4. Zida Zomangira:

• PVA 2488 ikhoza kupeza ntchito pamakampani omanga, makamaka ngati chowonjezera mumipangidwe ya simenti kuti ipititse patsogolo kumamatira ndi kusinthasintha.

5. Kuyika:

• Makanema a PVA, kuphatikiza omwe amachokera pa PVA 2488, amagwiritsidwa ntchito pamapaketi osungunuka ndi madzi.

6. Ntchito Zachipatala:

• PVA, kawirikawiri, imagwiritsidwa ntchito pazachipatala, kuphatikizapo kupanga magolovesi opangira opaleshoni komanso ngati chigawo cha mankhwala opangidwa ndi kutulutsidwa kwa mankhwala.

7. Emulsifiers:

• PVA 2488, yokhala ndi emulsifying katundu, itha kugwiritsidwa ntchito popanga ma emulsion.

Zoganizira:

1. Zokhudza Kapangidwe:

• Kusankhidwa kwa giredi ya PVA, kuphatikiza PVA 2488, zimatengera zomwe mukufuna kugwiritsa ntchito. Madigiri osiyanasiyana a hydrolysis ndi zolemetsa za mamolekyulu amapereka kusintha kwa magwiridwe antchito.

2. Kugwirizana:

• PVA 2488 nthawi zambiri imasankhidwa kutengera kuyanjana kwake ndi zosakaniza zina mu kapangidwe kake komanso kuthekera kwake kukwaniritsa zomwe mukufuna kuchita.

3. Malingaliro Opereka:

• Kugwira ntchito limodzi ndi ogulitsa ndi opanga PVA ndikofunikira kuti mupeze chitsogozo pakugwiritsa ntchito bwino kwa PVA 2488 pamapangidwe osiyanasiyana. Othandizira angapereke zidziwitso za njira zopangira komanso zogwirizana ndi zowonjezera zina.

Mwachidule, PVA 2488 ndi giredi yapadera ya Polyvinyl Mowa wokhala ndi mawonekedwe apadera omwe amaupanga kukhala oyenera kugwiritsa ntchito zosiyanasiyana, makamaka zomatira, nsalu, zokutira zamapepala, zida zomangira, ndi zina zambiri. Ngati muli ndi nkhani kapena ntchito inayake m'maganizo, kupereka zina zowonjezera kungathandize kuyankha molondola.
