Chosefera nsalu ndizosefera pazosindikiza. Tili ndi zida zathunthu zosefera zomwe zimapereka pakampani yamafuta osiyanasiyana yolimba-madzi. Timapereka nsalu yosanja yayikulu yosanja ya fyuluta ya gasket kapena mbale zopanda gasket, kukula kwa mbale kuchokera ku 315mm mpaka 2000mm, zosefera pazinthu zosiyanasiyana, monga PP (polypropylene), PE (polypropythane) kapena nayiloni, mu ulusi wosiyanasiyana wa ulusi ndi njira yokhotakhota, nsalu zosefera zonse zimabwera mwatsatanetsatane kukula kwa pore ndi malingaliro amtundu wa micron.

Sefani nsalu yosindikizira nthawi zambiri imaphatikizapo mitundu 4, polyester (terylene / PET), polypropylene (PP), chinlon (polyamide / nayiloni) ndi vinylon. Makamaka zinthu za PET ndi PP zimagwiritsidwa ntchito kwambiri.

Mbale chimango fyuluta atolankhani nsalu fyuluta ntchito kupatukana olimba madzi, choncho ali ndi lamulo apamwamba pa ntchito kukana onse asidi ndi soda, ndipo nthawi zina pa kutentha etc ...

Poliyesitala / PET Sefani Press Nsalu

Polyester Sefani Nsalu itha kugawidwa mu nsalu za PET, nsalu za ulusi wa PET ndi monofilament ya PET, izi zimakhala ndi mphamvu yolimba ya acid- kukana, kukana kwa alkali komanso kutentha kwapamwamba ndi digiri ya 130 centigrade. Amatha kugwiritsidwa ntchito kwambiri popanga mankhwala, osasungunuka mabwato, mafakitale opangira zida zamafyuluta amkati, zosefera za centrifuge, zosefera ndi zina. Kutsata mwatsatanetsatane kumatha kufikira 5microns.

Polypropylene / PP fyuluta Press nsalu

Zosefera za polypropylene zimakhala ndi mphamvu ya asidi-kukana, kukana kwa alkali, mphamvu yokoka yaying'ono, malo osungunuka 142-140centigrade degree, komanso kutentha kwapamwamba pazaka 90 za centigrade. Amagwiritsidwa ntchito makamaka mu mankhwala osakanikirana, mankhwala a utoto, shuga, mankhwala, makampani a alumina pazida zamafyuluta amakanema, zosefera lamba, zosefera lamba, zosefera zapa disc, zosewerera ng'oma ndi zina.
