Nchekwa nke Waterproof na Membrane na-eku ume
Mgbe a na-echekwa akpụkpọ anụ ahụ ruo ogologo oge, ọ ghaghị ịnọgide na-arụ ọrụ nke ọma ma nwee uru bara uru, ya mere ndụ nke mmiri na-ekpuchi mmiri na ume iku ume bụ ihe dị mkpa. Ya mere, a ga-akwụ ụgwọ nlebara anya pụrụ iche na nchekwa n'ezie.
A na-ekewa akpụkpọ ahụ microfiltration nke mmiri na-adịghị na-eku ume na ụzọ abụọ: nchekwa mmiri na nchekwa akọrọ. Kedu ụzọ ọ bụla, ebumnuche bụ igbochi akpụkpọ ahụ ka ọ bụrụ hydrolyzed, na-egbochi uto na mmebi nke microorganisms, na nkwụsịtụ na nrụrụ nke akpụkpọ ahụ.
Isi ihe na-echekwa mmiri mmiri bụ idowe elu akpụkpọ ahụ mgbe niile na ngwọta nchekwa na ọnọdụ mmiri mmiri. Enwere ike iji usoro na-esonụ maka ngwọta nchekwa: mmiri: glycerin: formaldehyde = 79.5: 20: 0.5. Ọrụ nke formaldehyde bụ igbochi uto na ịmụpụta microorganisms n'elu akpụkpọ ahụ yana igbochi mbuze nke akpụkpọ ahụ. Ebumnuche nke ịgbakwunye glycerin bụ iji belata ebe na-ekpo ọkụ nke ngwọta nchekwa ma gbochie akpụkpọ ahụ ka ọ ghara imebi site na oyi. Formaldehyde dị na usoro a nwekwara ike dochie ya na fungicides ndị ọzọ dị ka ọla kọpa sulfate na-adịghị emerụ akpụkpọ ahụ. Okpomọkụ nchekwa nke cellulose acetate membrane bụ 5-40 ° C na PH = 4.5 ~ 5, ebe nchekwa nchekwa na pH nke akpụkpọ anụ acetate na-abụghị cellulose nwere ike gbasaa.
Nchekwa akọrọ
A na-enyekarị akpụkpọ anụ microfiltration mmiri na-eku ume n'ahịa dị ka akpụkpọ anụ akọrọ n'ihi na ọ dị mfe ịchekwa na ibufe. Tụkwasị na nke ahụ, a ghaghị ịchekwa ihe nkiri mmiri ahụ na usoro akọrọ, a ghaghị iji usoro ndị a mee ihe iji dozie ihe nkiri ahụ tupu ya aga n'ihu. Usoro a kapịrị ọnụ bụ: cellulose acetate membrane nwere ike tinye ya na 50% glycerin aqueous solution ma ọ bụ 0.1% sodium lauryl sulfonate aqueous solution maka ụbọchị 5 ruo 6, wee kpoo ya na iru mmiri nke 88%. Enwere ike ịmịchaa akpụkpọ ahụ polysulfone na okpomọkụ nke ụlọ na ngwọta nke 10% glycerin, mmanụ sulfonated, polyethylene glycol, wdg dị ka onye na-eme ka mmiri na-ekpo ọkụ. Tụkwasị na nke ahụ, surfactants nwekwara mmetụta dị mma n'ichekwa pores nke ihe nkiri ahụ site na nrụrụ.
Nke abuo, nlebara anya na nlebara anya na nlebara anya na nlebara anya nke mmiri na-egbochi mmiri na iku ume
Nlekọta na mmezi nke usoro akpụkpọ ahụ kwesịrị ilekwasị anya n'okwu ndị a.
① Dị ka akpụkpọ anụ dị iche iche si dị, a ga-akwụ ụgwọ nlebara anya pụrụ iche na gburugburu ebe a na-eji ya eme ihe, karịsịa okpomọkụ na uru pH nke mmiri mmiri, na ọbụna chlorine dị n'ime mmiri mmiri.
② Mgbe usoro akpụkpọ ahụ kwụsịrị maka oge dị mkpirikpi, a ga-akwụ ụgwọ nlebara anya na njigide mmiri nke akpụkpọ ahụ, n'ihi na ozugbo akpụkpọ anụ ahụ na-efunahụ mmiri, ọ dịghị ihe ọ bụla na-emezigharị, mmiri na-ekpuchi mmiri na nke na-eku ume ga-adaba ma gbanwee, nke ga-ebelata arụ ọrụ akpụkpọ ahụ.
③Mgbe ị na-akwụsị, zere kọntaktị na mmiri mmiri na-etinye uche dị elu.
④ Jiri mmiri ndozi na-asachapụ ma na-echekwa akpụkpọ ahụ mgbe niile iji belata mmetọ akpụkpọ ahụ.
⑤ Na-eji, rụọ ọrụ dabere na ọnọdụ arụ ọrụ nke sistemu akpụkpọ ahụ nwere ike iguzogide iji zere ibufe ibu.
