Ịchọgharị PolyDADMAC

Ịchọpụta Mmekọrịta Dị n'etiti Ibu Mkpụrụ, Viscosity, Ọdịnaya siri ike, na Ogo nke PolyDADMAC

PolyDADMAC (a makwaara dịka "polydiallyl dimethyl ammonium chloride") bụ polima cationic eji eme ihe n'usoro ọgwụgwọ mmiri. A na-eji ya eme ihe maka ezigbo flocculation na coagulant. Dịka onye na-ebubata ma na-ekesa kemịkalụ ọgwụgwọ mmiri, ọ dị oke mkpa ịghọta mmekọrịta dị n'etiti ibu molekul, viscosity na ọdịnaya siri ike nke PolyDADMAC na ịdị mma ngwaahịa. N'isiokwu a, anyị ga-enyocha njikọ dị n'etiti ihe ngosi ndị a na otu esi ahọrọ ngwaahịa dị elu nke dabara gị.

Ibu molekul, viscosity na ọdịnaya siri ike nke PolyDADMAC bụ ihe ndị dị mkpa na-emetụta mmetụta ya. Ha nwere njikọ chiri anya. Ihe ndị a bụ nkọwa zuru ezu banyere ha na nkọwa zuru ezu nke mmekọrịta ha:

1. Mmekọrịta

Ibu arọ nke molekụla na-ezo aka n'ogologo ogologo nke PolyDADMAC polymer yinye.

Ibu molekul dị elu na-apụtakarị ogologo ígwè polymer, nke nwere ike ime ka ikike flocculation nke PolyDADMAC ka mma. Ibu molekul dị elu na-enye ụfọdụ mmetụta njikọ, na-ekwe ka obere ihe dị n'ime mmiri jikọọ ọnụ. Ọ nwere ike ime ka mmetụta ọgwụgwọ mmiri ka mma.

Agbanyeghị, oke ibu nke molekul nwekwara ike ibute oke viscosity, nke na-emetụta ọrụ.

Ibu molekụla bụ ihe dị mkpa na-egosi àgwà PDADMAC n'ihi na ọ na-emetụta mmetụta ngwa ya ozugbo.

Ibu molekul PDADMAC na-adịkarị site na 50,000 ruo 700,000Da, ngwaahịa ndị nwere oke ibu molekul kwesịrị ịkarị oke na 3,000,000Da.

2. Viscositi

Viscosity na-ezo aka na iguzogide nke ngwọta PolyDADMAC iji na-asọ.

N'ozuzu, viscosity bụ 80-12,000mPa.s, e nwekwara PolyDADMAC dị elu nke nwere viscosity karịrị 100,000. Viscosity nwere njikọ chiri anya na ibu molekul, ibu molekul dị elu na-ebute viscosity dị elu. Viscosity na-emetụtakwa ịgbaze na ịgbaze nke PDADMAC, yana arụmọrụ ọrụ ya na ngwa. Ọ bụrụ na viscosity dị oke elu, viscosity dị elu ga-akpata ụfọdụ nsogbu ọrụ (ịnyefe na ịgbaze, wdg.). Viscosity bụ paramita dị mkpa maka ịtụ àgwà PDADMAC n'ihi na ọ na-egosipụta ibu molekul ya na arụmọrụ ngwa ya., ebe obere viscosity PolyDADMAC nwere ezigbo mmiri mmiri ma dị mfe ịgba.

3. Ọdịnaya siri ike

Ọdịnaya siri ike na-ezo aka na pasentị ibu nke polima dị na ngwọta PolyDADMAC.

Oke ọdịnaya siri ike pụtara mbelata ọnụ ahịa nchekwa na ibu. Agbanyeghị, ọ bụrụ na a kwadebe ngwaahịa nwere oke ibu molekul dị ka ngwọta 40%, a pụghị ọbụna ịwụpụ ya na drum ahụ.

Ọdịnaya siri ike nke PolyDADMAC bụ 10% ma ọ bụ 50%, ya bụ, oke nke ihe ndị dị irè n'ezie na ngwọta ahụ.

Ọtụtụ mgbe, ọdịnaya siri ike nke PolyDADMAC anyị na-ere bụ ihe dị ka 40%. Anyị nwekwara nkọwapụta ọdịnaya siri ike ndị ọzọ.

Ị nwere ike ịlelenkọwa zuru ezu nke ngwaahịa PolyDADMACmaka nkọwapụta kpọmkwem na ihe ngosi zuru ezu nke PolyDADMAC.

Mmekọrịta dị n'etiti ha:

Ibu na viscosity nke molekụla:

Maka otu ihe siri ike ahụ, ka ibu arọ nke molekul dị elu, otú ahụ ka viscosity ahụ si ka mma.

Ka ibu arọ nke molekul buru ibu, otú ahụ ka viscosity dị elu.

Ọdịnaya siri ike na viscosity:

Maka otu ibu molekul ahụ, ka ọdịnaya siri ike dị elu, otú ahụ ka viscosity ahụ si ka mma.

Ibu molekul, ọdịnaya siri ike, na arụmọrụ:

N'ihe siri ike ụfọdụ, ka ibu molekul dị elu, otú ahụ ka mmetụta ya ga-aka mma, mana viscosity ga-abawanye.

Otu esi ahọrọ PolyDADMAC nke dabara gị

Viskọst ezi uche dị na ya: hụ na mmiri mmiri dị, mfe ịgbaze, yana arụmọrụ dị mma nke flocculation.

Ọ bụrụ na ịchọrọ ịchọta onye na-ebubata ngwaahịa ọhụrụ iji zụta PolyDADMAC, buru ụzọ chọpụta ụdị mmiri ị na-eji ka onye na-ebubata ngwaahịa gị wee nwee ike inyere gị aka ịhọrọ ụdị ka mma. Ma ọ bụ ị nwere ike ịgwa onye na-ebubata ngwaahịa aha na ụdị PolyDADMAC ị jirila na mbụ. Ma ọ bụ ị nwere ike izipu PolyDADMAC gị dị ugbu a na onye na-ebubata ngwaahịa ọhụrụ gị ma kwe ka ha nyere gị aka inyocha ma họrọ. Nnwale ihe nlele nke PolyDADMAC ọhụrụ dị oke mkpa, ị ga-emekwa nnwale ahụ nke ọma iji chọpụta ma ụdị ahụ ọ dabara gị nke ọma.
