Gwiritsani ntchito HPMC kuthana ndi kuthwanima ndi kutuluka thovu kwa khoma la putty

Wall putty ndi gawo lofunikira kwambiri pakujambula. Ndi chisakanizo cha zomangira, zodzaza, ma pigment ndi zowonjezera zomwe zimapangitsa kuti pamwamba pakhale bwino. Komabe, pakumanga khoma la putty, mavuto ena omwe amapezeka nthawi zambiri amatha kuwoneka, monga kutulutsa, kutulutsa thovu, ndi zina zambiri. Deburring ndikuchotsa zinthu zochulukirapo kuchokera pamwamba, pomwe matuza ndikupanga timatumba tating'ono ta mpweya pamwamba. Nkhani zonsezi zingakhudze maonekedwe omaliza a makoma ojambulidwa. Komabe, pali njira yothetsera mavutowa - gwiritsani ntchito HPMC mu khoma la putty.

HPMC imayimira hydroxypropyl methylcellulose. Ndi gulu lomwe limagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikiza zomangamanga. HPMC ndi chowonjezera chabwino cha ma putties a khoma chifukwa imathandizira kugwirira ntchito, mgwirizano ndi mphamvu zosakaniza. Ubwino umodzi wogwiritsa ntchito HPMC ndikutha kuchepetsa kutulutsa ndi matuza. Nayi kufotokozera momwe HPMC ingathandizire kuthetsa izi:

Deburring

Deburring ndi vuto lofala mukamagwiritsa ntchito wall putty. Izi zimachitika pamene pali zinthu zowonjezera pamwamba zomwe ziyenera kuchotsedwa. Izi zitha kupangitsa kuti pakhale malo osagwirizana komanso kugawa utoto kosagwirizana pojambula makoma. HPMC ikhoza kuwonjezeredwa ku zosakaniza za khoma kuti zisawonongeke.

HPMC imagwira ntchito ngati retarder mu khoma putty, kuchepetsa nthawi yowuma ya osakaniza. Izi zimathandiza putty nthawi yokwanira kukhazikika pamwamba popanda owonjezera zinthu kupanga. Ndi HPMC, kusakaniza kwa putty kumatha kuyikidwa mugawo limodzi popanda kubwereza.

Komanso, HPMC kumawonjezera kukhuthala wonse wa khoma putty osakaniza. Izi zikutanthauza kuti kusakaniza kumakhala kokhazikika komanso kosavuta kupatukana kapena kuphatikiza. Chotsatira chake, kusakaniza kwa khoma la putty kumakhala kosavuta kugwira ntchito ndikufalikira mosavuta pamwamba, kuchepetsa kufunikira kwa deburring.

kubwebweta

Blisting ndi vuto lina lomwe limachitika pomanga khoma la putty. Izi zimachitika pamene putty imapanga timatumba tating'ono ta mpweya pamwamba pamene ikuuma. Ma matumba a mpweyawa amatha kuyambitsa malo osagwirizana ndikuwononga mawonekedwe omaliza a khoma akapaka utoto. HPMC ingathandize kuteteza thovu izi kuti zisapangike.

HPMC imachita ngati filimu yakale mu wall putty. Putty ikauma, imapanga filimu yopyapyala pamwamba pa putty. Kanemayu amakhala ngati chotchinga, kuteteza chinyezi kulowa mozama mu khoma putty ndikupanga matumba mpweya.

Kuphatikiza apo, HPMC imawonjezeranso mphamvu yolumikizira khoma la putty pamwamba. Izi zikutanthauza kuti putty amamatira bwino pamwamba, kuchepetsa mapangidwe a matumba a mpweya kapena mipata pakati pa putty ndi pamwamba. Ndi HPMC, kusakaniza kwa khoma la putty kumapanga mgwirizano wolimba ndi pamwamba, kuteteza matuza kuti asachitike.

Pomaliza

Wall putty ndi gawo lofunika kwambiri pojambula, ndipo ndikofunikira kuonetsetsa kuti limatha bwino. Kuchitika kwa kuwonongeka ndi matuza kungakhudze mawonekedwe omaliza a khoma lopaka utoto. Komabe, kugwiritsa ntchito HPMC monga chowonjezera ku khoma la putty kungathandize kuthetsa mavutowa. HPMC imagwira ntchito ngati seti retarder, kuonjezera mamasukidwe akayendedwe osakaniza ndi kuteteza zinthu owonjezera kupanga pamwamba. Panthawi imodzimodziyo, zimathandiza kupanga mgwirizano wamphamvu pakati pa khoma la putty ndi pamwamba, kuteteza mapangidwe a matumba a mpweya ndi thovu. Kugwiritsiridwa ntchito kwa HPMC mu khoma la putty kumatsimikizira kuti mawonekedwe omaliza a khoma lopaka utoto ndi osalala, ngakhale angwiro.
