2025-02-24
Zimayambitsa:
1. Mavuto abwino ndi magwiridwe antchito azinthu zopangira
2.Kuuma koipa
3. Kutentha kwa mbiya ndi kwakukulu kwambiri (> 285 ℃)
4.Kupanikizika kwa screw backpressure kwakukulu kwambiri
5. Nthawi yozungulira ndi yayitali kwambiri
Mayankho：
1. Kuyang'anira ubwino wa zipangizo zopangira zisanalowe m'nyumba yosungiramo katundu
2. Yang'anani momwe choumitsira chimagwirira ntchito (monga mame, kutentha/nthawi youma)
3. Sungani kutentha kotsika momwe mungathere pamene mukusunga khalidwe
4. Ikani mphamvu yakumbuyo pa (400-600psi) bola ngati khalidwe lake likusungidwa bwino
5. Kukonza nthawi yozungulira (kupewa nthawi yochulukirapo yokhalamo ya zosaphika
zinthu zomwe zili mu screw)
Iyi ndi njira yothetsera vutoli. Mavuto omwe amakumana nawo tsiku ndi tsiku njira yopangira zinthu idzafotokozedwa mwatsatanetsatane.
Mwachitsanzo, pofufuza zinthu zopangira, tingafunike kudziwakuchuluka kwa chinyezi, kukhuthala kwa mkati (IV value), kukhazikika kwa kutentha, ndi zina zotero. kwa zosaphikazipangizo;

Kuti tikwaniritse bwino njira yowumitsa, nthawi zonse timayesagawo lochotsa chinyezi cha chowumitsira, kutentha kowumitsa, ndi malo osungiramuyezo mutaumitsa zipangizo zopangira, ndi zina zotero. Ngati vutoli silikubuka, tiyenera kuliletsa, ndipo
pamene vutozikachitika, tiyenera kuzithetsa.
