Zofunikira pakugwira ntchito kwa zingwe za sitima

Zingwe za sitima zapamtunda ndi za zingwe zapadera ndipo zimakumana ndi malo osiyanasiyana achilengedwe ovuta akagwiritsidwa ntchito.

Izi zikuphatikizapo kusintha kwakukulu kwa kutentha pakati pa usana ndi usiku, kuwala kwa dzuwa, nyengo, chinyezi, mvula ya asidi, kuzizira, madzi a m'nyanja, ndi zina zotero. Zinthu zonsezi zingakhudze kwambiri moyo wa chingwe ndi magwiridwe antchito ake, ngakhale kuchepetsa kudalirika kwake komanso chitetezo chake, zomwe zimapangitsa kuti katundu awonongeke komanso kuvulala kwa munthu.

Chifukwa chake, zingwe zoyendera sitima ziyenera kukhala ndi makhalidwe oyambira awa:

1. Utsi wochepa, wopanda halogen, komanso woletsa moto

Kupanga utsi wochepa kwambiri panthawi yoyaka chingwe, kutulutsa kuwala ≥70%, kusapanga zinthu zoopsa monga ma halogen omwe amawononga thanzi la anthu, komanso pH ≥4.3 panthawi yoyaka.

Katundu woletsa moto ayenera kukwaniritsa zofunikira za mayeso oyatsa moto pogwiritsa ntchito chingwe chimodzi, mayeso oyatsa moto pogwiritsa ntchito chingwe chimodzi, ndi mayeso oyatsa moto pogwiritsa ntchito chingwe chimodzi pambuyo poti mafuta alephera.

 

2. Wokhala ndi makoma ochepa,magwiridwe antchito apamwamba amakina

Zingwe za malo apadera zimafuna makulidwe ochepa a insulation, opepuka, osinthasintha kwambiri, okana kupindika, komanso okana kukalamba, ndipo zimafuna mphamvu zambiri zokoka.

 

3. Kukana madzi, kukana asidi-alkali, kukana mafuta, kukana ozoni

Unikani kusintha kwa mphamvu yokoka ndi kuchuluka kwa zingwe zomwe zimatalika pambuyo pa kukana mafuta. Zinthu zina zimayesedwa mphamvu ya dielectric pambuyo pa kukana mafuta.

 

4. Kukana kutentha kwambiri, kukana kutentha kochepa

Zingwe zimasunga bwino kwambiri makina m'malo otentha kwambiri kapena otsika kwambiri popanda kusweka pambuyo pokumana ndi kutentha kwakukulu kapena kotsika.
