Gawo la Mafunso Ofunsidwa Kawirikawiri

Q1: N’chifukwa chiyani HPMC ndi yofunika kwambiri mu matope oteteza kutentha?

HPMC imapangitsa kuti madzi azisungidwa bwino, azigwira ntchito bwino, komanso kuti madzi asagwe, zomwe zimathandiza kuti madziwo azigwiritsidwa ntchito bwino komanso kuti madziwo azigwira ntchito bwino.

Q2: Kodi ntchito yaikulu ya RDP ndi yotani?

RDP imawonjezera kumamatira, kusinthasintha, komanso kukana ming'alu mwa kupanga filimu ya polima mkati mwa matope.

Q3: N’chifukwa chiyani mumagwiritsa ntchito ulusi wa polypropylene?

Ulusi wa PP umawongolera kusweka kwa ming'alu ndipo umawonjezera mphamvu ya makina komanso kulimba.

Q4: Kodi matope oteteza kutentha angagwire ntchito popanda zowonjezera?

Inde, koma magwiridwe antchito ake sangakhale abwino—osagwirana bwino, osweka kwambiri, komanso ofooka.

Q5: Ndi chowonjezera chiti chomwe chili chofunikira kwambiri?

Zonse zitatu ndizofunikira:

· HPMC = magwiridwe antchito atsopano
· RDP = mphamvu yolumikizana
· Ulusi wa PP = kulimbitsa kapangidwe kake
