Kodi Wall putty ndi chiyani?

Wall putty ndi mtundu wazinthu zomwe zimagwiritsidwa ntchito kusalaza pamwamba pa makoma podzaza mipata ndikuwongolera. Ndi ufa wopangidwa ndi simenti womwe umasakanizidwa ndi madzi kuti ukhale wofanana ndi phala womwe ungagwiritsidwe ntchito pamakoma. Chimodzi mwazinthu zofunika kwambiri pa khoma la putty ndi cellulose ether.

Cellulose ether ndi polima wosungunuka m'madzi wochokera ku cellulose wachilengedwe. Amapangidwa ndi cellulose yosintha mankhwala, yomwe ndi polima yopezeka mwachilengedwe yomwe imapezeka m'makoma a cellulose. Ma cellulose ether amagwiritsidwa ntchito kwambiri pantchito yomanga ngati thickener, stabilizer, binder, ndi wosunga madzi. Amagwiritsidwanso ntchito popanga zinthu zosiyanasiyana zogula, monga chakudya, zodzoladzola, ndi mankhwala.

Pankhani ya putty wall, cellulose ether imakhala ngati thickener ndi binder. Ma cellulose ether akawonjezeredwa pa khoma la putty osakaniza, amawongolera magwiridwe antchito ake popereka kusasinthika kosalala. Izi zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito putty pamakoma ndikuonetsetsa kuti zimamatira bwino pamwamba. Cellulose ether imathandizanso kupewa kuchepa komanso kusweka kwa khoma la putty likawuma.

Udindo wina wofunikira wa cellulose ether mu khoma putty ndikutha kusunga madzi. Wall putty imayenera kukhala yonyowa kwa nthawi yayitali mukatha kugwiritsa ntchito kuti iwonetsetse kuti imauma bwino ndikupanga mgwirizano wolimba ndi khoma. Cellulose ether imathandizira kusunga madzi mu chisakanizo cha putty, chomwe chimachepetsa kuyanika ndikuwonetsetsa kuti putty ikhazikika bwino.

Ubwino ndi magwiridwe antchito a khoma la putty zimakhudzidwa kwambiri ndi mtundu ndi kuchuluka kwa cellulose ether yomwe imagwiritsidwa ntchito. Pali mitundu yosiyanasiyana ya etha ya cellulose yomwe ikupezeka pamsika, monga hydroxyethyl cellulose (HEC), methyl cellulose (MC), ndi carboxymethyl cellulose (CMC). Mtundu uliwonse uli ndi mawonekedwe ndi mawonekedwe osiyanasiyana, ndipo kusankha mtundu woyenera ndi kuchuluka kwake ndikofunikira pakuzindikira mtundu wa khoma la putty.

Mwachidule, cellulose ether imagwira ntchito yofunika kwambiri popanga khoma la putty. Amapereka zofunikira zowonjezera, zomangiriza, ndi zosungira madzi kusakaniza kwa putty, zomwe zimatsimikizira kuti zimagwira ntchito, zimalepheretsa kuchepa ndi kusweka, ndikuonetsetsa kuti kuyanika koyenera ndi kugwirizanitsa pamwamba pa khoma. Kusankha mtundu woyenera ndi kuchuluka kwa cellulose ether ndikofunikira popanga putty wapamwamba kwambiri wa khoma lomwe limakwaniritsa zofunikira zamakampani omanga.
