Momwe Mungasankhire Zosefera

1. Pa fyuluta

Monga momwe dzinalo likusonyezera, zosefera zimagwiritsidwa ntchito posefa zamadzimadzi kapena mpweya ndi madzi ena.Ntchito yake yayikulu ndikusefa, kuti akwaniritse cholinga cha ogwiritsa ntchito.

2. Pa gulu la zosefera

Zosefera zimagawidwa m'magulu awiri malinga ndi zofunikira zawo.

1. coarse fyuluta, yomwe imadziwikanso kuti pre fyuluta.Kusiyana kwakukulu ndikuti kusefa kwawo kumakhala kokulirapo kuposa ma microns 100 (100um mpaka 10mm…).;

2. fyuluta yolondola, yomwe imadziwikanso kuti fyuluta yabwino.Kusiyana kwakukulu ndikuti kusefa kwawo kolondola nthawi zambiri kumakhala kosakwana ma microns 100 (100um~0.22um).

Malinga ndi zofunikira zakuthupi, fyulutayo imagawidwa m'magulu atatu:

1. carbon steel chuma (zida wamba, monga Q235., A3, 20 #, etc.), makamaka ntchito zikuwononga zamadzimadzi kapena mpweya ndi zina zotero.Inde, monga fyuluta kwa mbali pachiwopsezo.Nthawi zambiri amapangidwa ndi chitsulo chosapanga dzimbiri.

2. zitsulo zosapanga dzimbiri (monga 304, 316, etc.), zomwe zimagwiritsidwa ntchito makamaka pazinthu zowonongeka.Cholinga chake ndi chakuti zipangizozi zikhoza kulekerera.Choseferacho chimapangidwa ndi chitsulo chosapanga dzimbiri, titaniyamu kapena PP.

3. Zida za PP (monga polypropylene, polytetrafluoro, kuphatikizapo fluorine lining kapena lining PO, etc.) zimagwiritsidwa ntchito makamaka mu mankhwala monga asidi, alkali, mchere ndi zina zotero.Chosefera pachimake nthawi zambiri chimakhala polypropylene.

Malinga ndi kukakamizidwa, fyulutayo imagawidwa m'magulu atatu:

1. kuthamanga otsika: 0 ~ 1.0MPa.

2. kuthamanga kwapakati: 1.6MPa mpaka 2.5MPa.

3. kuthamanga kwambiri: 2.5MPa mpaka 11.0MPa.
