Kodi zopangira za wall putty ndi chiyani?

Wall putty ndi zida zomangira zodziwika bwino zomwe zimagwiritsidwa ntchito mnyumba zogona komanso zamalonda. Ndizinthu zosunthika zomwe zimagwiritsidwa ntchito kusalaza ndi kumaliza makoma amkati ndi akunja musanayambe kujambula kapena kujambula. Wall putty amapangidwa ndi zinthu zosiyanasiyana zopangira zomwe zimasakanizidwa kuti zipange chinthu chakuda ngati phala. M'nkhaniyi, tikambirana mwatsatanetsatane zipangizo za wall putty.

Simenti yoyera:
Simenti yoyera ndiye chinthu choyambirira chomwe chimagwiritsidwa ntchito mu khoma la putty. Ndi chomangira cha hydraulic chomwe chimapangidwa kuchokera ku clinker yoyera pansi komanso gypsum. Simenti yoyera imakhala yoyera kwambiri komanso imakhala yochepa kwambiri yachitsulo ndi manganese oxide. Imayamikiridwa mu khoma la putty chifukwa imakhala yosalala pamakoma, imakhala ndi zomatira zabwino, komanso imalimbana ndi madzi.

Ufa wa nsangalabwi:
Ufa wa nsangalabwi ndi wopangidwa kuchokera ku kudula ndi kupukuta nsangalabwi. Ndiwopukuta bwino ndipo amagwiritsidwa ntchito mu khoma la putty kuti likhale lolimba komanso lolimba. Ufa wa nsangalabwi ndi mchere wachilengedwe womwe uli ndi kashiamu wochuluka ndipo umakhala ndi mgwirizano wabwino. Zimathandizira kuchepetsa kuchepa kwa putty ndikupangitsa kuti makomawo azikhala osalala.

Talcum powder:
Talcum ufa ndi mchere wofewa womwe umagwiritsidwa ntchito mu khoma la putty kuti ugwire ntchito bwino komanso kuchepetsa kukhuthala kwa kusakaniza. Ndiwophwanyidwa bwino ndipo ndi woyera kwambiri. Ufa wa Talcum umathandizira kugwiritsa ntchito mosavuta putty ndikuwongolera kumamatira kwake pamakoma.

China Clay:
Dongo la China, lomwe limadziwikanso kuti kaolin, ndi mchere wachilengedwe womwe umagwiritsidwa ntchito mu khoma la putty ngati chodzaza. Ndiwophwanyidwa bwino ndipo ndi woyera kwambiri. Dongo la China ndi chinthu chotsika mtengo chomwe chimagwiritsidwa ntchito kukonza kuchuluka kwa putty ndikuchepetsa mtengo wake.

Mica powder:
Mica powder ndi mchere wachilengedwe womwe umagwiritsidwa ntchito mu khoma la putty kuti ukhale wonyezimira pamakoma. Ndi bwino pansi ndipo ali ndi mlingo wapamwamba wa reflectivity. Mica powder imathandizira kuchepetsa porosity ya putty ndipo imapereka kukana bwino kwa madzi.

Mchenga wa silika:
Mchenga wa silika ndi mchere wachilengedwe womwe umagwiritsidwa ntchito mu khoma la putty ngati chodzaza. Ndiwophwanyidwa bwino ndipo ndi woyera kwambiri. Mchenga wa silika umathandizira kukulitsa mphamvu ya putty ndikuchepetsa kuchepa kwake. Zimathandizanso kuwongolera kumamatira kwa putty kumakoma.

Madzi:
Madzi ndi gawo lofunikira pa khoma la putty. Amagwiritsidwa ntchito kusakaniza zopangira pamodzi ndikupanga chinthu chonga phala. Madzi amathandiza activating amamanga katundu wa simenti ndi amapereka fluidity zofunika kusakaniza.

Zowonjezera Chemical:
Zowonjezera za Chemical zimagwiritsidwa ntchito mu wall putty kuti zisinthe mawonekedwe ake ndi magwiridwe ake. Zina mwa zinthu zimenezi ndi monga ma retarders, ma accelerator, mapulasitiki, ndi zinthu zotsekereza madzi. Ma retarders amagwiritsidwa ntchito kuchepetsa nthawi yoyika putty, pomwe ma accelerators amagwiritsidwa ntchito kufulumizitsa nthawi yoyika. Pulasitiki amagwiritsidwa ntchito kuti azitha kugwira ntchito bwino komanso kuchepetsa kukhuthala kwa putty, pomwe zotchingira madzi zimagwiritsidwa ntchito popanga putty kusagwira madzi.

Methyl cellulosendi mtundu wamba wa cellulose ether womwe umagwiritsidwa ntchito mu wall putty. Amapangidwa ndi kusintha kwa mankhwala a cellulose achilengedwe pogwiritsa ntchito methanol ndi alkali. Methyl cellulose ndi ufa woyera, wopanda fungo, komanso wopanda kukoma womwe umasungunuka m'madzi ndikupanga yankho lomveka bwino komanso lowoneka bwino. Imakhala ndi zinthu zabwino zosungira madzi ndipo imapangitsa kuti putty ikhale yogwira ntchito. Methyl cellulose imaperekanso kumamatira kwabwino kwa magawo osiyanasiyana komanso kumapangitsa kuti ma putty azilimba.

Hydroxyethyl cellulose ndi mtundu wina wa cellulose ether womwe umagwiritsidwa ntchito mu khoma la putty. Zimapangidwa ndi kusintha kwa mankhwala a cellulose yachilengedwe pogwiritsa ntchito ethylene oxide ndi alkali. Hydroxyethyl cellulose ndi ufa woyera, wopanda fungo, komanso wopanda kukoma womwe umasungunuka m'madzi ndikupanga yankho lomveka bwino komanso lowoneka bwino. Imakhala ndi zinthu zabwino zosungira madzi ndipo imapangitsa kuti putty ikhale yogwira ntchito. Hydroxyethyl cellulose imaperekanso kumamatira kwabwino ku magawo osiyanasiyana ndikuwongolera mphamvu zamakomedwe a putty.

Carboxymethyl cellulose imagwiritsidwanso ntchito mu khoma la putty ngati thickener ndi binder. Amapangidwa ndi kusinthidwa kwa mankhwala a cellulose achilengedwe pogwiritsa ntchito monochloroacetic acid ndi alkali. Carboxymethyl cellulose ndi ufa woyera, wopanda fungo, komanso wopanda kukoma womwe umasungunuka m'madzi ndikupanga yankho lomveka bwino komanso lowoneka bwino. Imakhala ndi zinthu zabwino zosungira madzi ndipo imapangitsa kuti putty ikhale yogwira ntchito. Carboxymethyl cellulose imaperekanso kumamatira kwabwino ku magawo osiyanasiyana ndikuwongolera mphamvu zamakomedwe a putty.

Pomaliza, khoma la putty limapangidwa ndi zida zosiyanasiyana zomwe zimasakanizidwa kuti zipange chinthu chonga phala. Zopangira zazikulu zomwe zimagwiritsidwa ntchito pakhoma putty ndi simenti yoyera, pomwe zida zina zimaphatikizapo ufa wa nsangalabwi, ufa wa talcum, dongo la china, ufa wa mica, mchenga wa silika, madzi, ndi zowonjezera zamankhwala. Zopangira izi zimasankhidwa chifukwa cha zinthu zake zenizeni, monga zoyera, zomangira, zogwira ntchito, komanso zolimba, kuti zipereke makoma osalala komanso onyezimira.
