Ibyiza na Viscosity bya CMC

Inzoga ya Polyvinyl (PVA) ni polymer ikoreshwa cyane isanga porogaramu nka kole cyangwa ifata mu nganda zitandukanye. Hano hari ibintu by'ingenzi byerekeranye n'inzoga za Polyvinyl nka kole:

1. Amazi-Amazi:

PVA irashobora gushonga amazi, bivuze ko ishobora gushonga byoroshye mumazi kugirango ibe igisubizo kiboneye. Uyu mutungo utuma PVA kole yoroshye kuyikoresha kandi itanga isuku yoroshye hamwe namazi.

2. Ntabwo ari uburozi kandi butekanye:

Ubusanzwe PVA ntabwo ari uburozi kandi ifite umutekano kugirango ikoreshwe mubikorwa bitandukanye, harimo ubuhanzi nubukorikori, gukora ibiti, nimishinga yimpapuro. Bikunze guhitamo gukoreshwa mumashuri, ingo, na DIY imishinga kubera imiterere yumutekano.

3. Ibifatika byinshi:

PVA kole yerekana neza cyane muburyo butandukanye, harimo impapuro, ibiti, imyenda, ikarito, nibikoresho byoroshye. Bikunze gukoreshwa muguhuza impapuro, ikarito, nimbaho ​​mubukorikori, gukora ibiti, guhuza ibitabo, hamwe no gupakira.

4. Kuma neza:

PVA kole yumye kugeza mu mucyo cyangwa mu mucyo, nta bisigara bigaragara cyangwa ibara risa neza. Ibi bituma biba byiza mubikorwa aho ubwiza bwingenzi, nkubukorikori bwimpapuro, kolage, hamwe nimishinga yo gushushanya.

5. Inkunga ikomeye:

Iyo ushyizwe neza kandi ukemererwa gukama, kole ya PVA ikora umurunga ukomeye kandi uramba hagati ya substrate. Itanga uburyo bwiza bwambere bwo gukomera no gufatira hamwe, hamwe nimbaraga nziza zingirakamaro mugihe.

6. Ibintu bihinduka:

Imiterere ya kole ya PVA irashobora guhindurwa muguhindura ibintu nko kwibanda, kwiyegeranya, ninyongera. Ibi bituma uhinduranya kole kugirango uhuze ibisabwa byihariye, nkibisabwa imbaraga zingirakamaro, igihe cyo kumisha, kandi byoroshye.

7. Bishingiye ku mazi kandi byangiza ibidukikije:

PVA kole ishingiye ku mazi kandi ntabwo irimo ibinyabuzima bihindagurika (VOC) cyangwa imiti yangiza, bigatuma itangiza ibidukikije. Irashobora kwangirika kandi irashobora gutabwa neza muri sisitemu yimyanda myinshi.

8. Gusaba:

PVA kole ikoreshwa muburyo butandukanye bwa porogaramu, harimo:

• Ubuhanzi nubukorikori: kolage, impapuro impapuro, ibitabo byanditse
• Gukora ibiti: gufatanya, kubaha, kumurika
• Guhuza ibitabo: guhuza impapuro n'ibitabo
• Gupakira: gufunga amakarito agasanduku, amakarito, n'ibahasha
• Imyenda: guhuza imyenda mu kudoda no gukora imyenda

9. Ibihinduka nuburyo bukurikira:

PVA kole iraboneka muburyo butandukanye, harimo amazi, gel, nuburyo bukomeye. Irashobora kandi guhindurwa hamwe ninyongeramusaruro nka plasitike, kubyimbye, hamwe no guhuza ibikorwa kugirango byongere ibintu byihariye cyangwa ibiranga imikorere.

Umwanzuro:

Inzoga ya Polyvinyl (PVA) ni ibifata byinshi kandi bifata ibintu byinshi mubukorikori n'ubukorikori, gukora ibiti, gupakira, imyenda, n'inganda. Imiterere yacyo yamazi, kutagira uburozi, guhinduranya, hamwe nuburyo bukomeye bwo guhuza bituma ihitamo gukundwa no guhuza insimburangingo zitandukanye mubikorwa bitandukanye. Byaba bikoreshwa mumashuri, ingo, cyangwa inganda, PVA glue itanga igisubizo cyizewe kandi cyiza cyo guhuza no gukenera guterana.
