Otu esi ahọrọ nzacha sirinji

Ebumnuche bụ isi nke nzacha sirinji bụ iji nzacha mmiri mmiri ma wepụ ihe dị iche iche, sedimenti, microorganisms, wdg. A na-ejikarị ha eme ihe na bayoloji, kemistri, sayensị gburugburu ebe obibi, ọgwụ na ọgwụ.Ihe nzacha a na-ewu ewu nke ukwuu maka mmetụta nzacha ya dị mma, ịdị mma na arụmọrụ ya.Agbanyeghị, ịhọrọ nzacha sirinji ziri ezi adịghị mfe ma na-achọ ịghọta njirimara nke membranes nzacha dị iche iche na ihe ndị ọzọ metụtara ya.Isiokwu a ga-enyocha ojiji nke nzacha agịga, njirimara nke ihe dị iche iche nke akpụkpọ ahụ, na otu esi eme nhọrọ ziri ezi.

• Ogo pore nke akpụkpọ ahụ nzacha

1) Nzacha akpụkpọ ahụ nwere oke nha nke 0.45 μm: ejiri ya mee ihe maka nzacha usoro mkpanaka oge niile ma nwee ike izute ihe achọrọ chromatographic izugbe.

2) Ihe nzacha akpụkpọ ahụ nwere oghere nke 0.22μm: Ọ nwere ike wepụ ihe dị oke mma na nlele na usoro mkpanaka yana wepụ microorganisms.

• Dayameta nke akpụkpọ ahụ nzacha

N'ozuzu, dayameta akpụkpọ anụ nzacha a na-ejikarị bụ Φ13μm na Φ25μm.Maka ihe atụ nke 0-10ml, Φ13μm nwere ike iji, na maka ihe atụ nke 10-100ml, Φ25μm nwere ike iji.

• Polyethersulfone (PES)

Atụmatụ: Akpụkpọ ahụ nzacha hydrophilic nwere njirimara nke ọnụ ọgụgụ dị elu, ihe ndị na-emepụta ihe dị ala, ike dị mma, anaghị akwado protein na extracts, ọ nweghịkwa mmetọ na nlele ahụ.

Ngwa: Ezubere maka biochemistry, nnwale, ọgwụ na sterile filtration.

• Ngwakọta cellulose esters (MCE)

Atụmatụ: Uniform pore size, elu porosity, enweghị mgbasa ozi mgbasa ozi, mkpa udidi, ala nguzogide, ngwa ngwa filtration ọsọ, ntakiri adsorption, ọnụ ala na ọnụ ahịa, ma ọ bụghị eguzogide organic ngwọta na ike acid na alkali ngwọta.

Ngwa: Nchacha nke ngwọta mmiri ma ọ bụ igba ogwu nke nkwadebe ndị na-ekpo ọkụ.

• akpụkpọ ahụ naịlọn (Nylon)

Atụmatụ: Ezi okpomọkụ na-eguzogide, nwere ike idi 121 ℃ jupụtara uzuoku na-ekpo ọkụ mgbali sterilization maka nkeji 30, ezigbo kemịkalụ kwụsie ike, nwere ike idi dilute acid, itughari alkali, alcohols, esters, mmanụ, hydrocarbons, halogenated hydrocarbons na organic oxidation A dịgasị iche iche nke organic na inorganic. ngwakọta.

Ngwa: nzacha nke aqueous ngwọta na organic mobile usoro.

• Polytetrafluoroethylene (PTFE)

Atụmatụ: Ngwakọta kemịkalụ kachasị obosara, nwere ike iguzogide ihe mgbaze organic dị ka DMSO, THF, DMF, methylene chloride, chloroform, wdg.

Ngwa: Nchacha ihe ngwọta organic niile na acid siri ike na ntọala, ọkachasị ihe mgbaze siri ike nke membranes nzacha ndị ọzọ enweghị ike ịnabata.

• Polyvinylidene fluoride akpụkpọ anụ (PVDF)

Atụmatụ: Akpụkpọ ahụ nwere ike nrụpụta dị elu, ezigbo nguzogide okpomọkụ na nkwụsi ike nke kemịkal, yana ọnụego mgbasa ozi protein dị ala;ọ nwere ike ọjọọ electrostatic Njirimara na hydrophobicity;mana ọ nweghị ike ịnabata acetone, dichloromethane, chloroform, DMSO, wdg.

Ngwa: A na-ejikarị akpụkpọ anụ PVDF hydrophobic maka gas na uzuoku filtration, na mmiri ọkụ dị elu.A na-ejikarị akpụkpọ ahụ PVDF hydrophilic maka ọgwụgwọ na-adịghị mma nke mgbasa ozi omenala anụ ahụ na ngwọta, nzacha mmiri ọkụ dị elu, wdg.
