Ihe dị iche iche nke viscosis ada n'oge nchekwa ihe bụ nsogbu a na-ahụkarị, ọkachasị ebe nchekwa, visses nke ihe na-ebelata arụmọrụ na ogo ngwaahịa. Ibelata viscosity metụtara ọtụtụ ihe, dịka okpomọkụ, iru mmiri, na-agbaze ọbara, ma na-emekọrịta ya na ndị na-emekọ ihe na-eto eto na-eto eto.
1. Ọrụ dị mkpa nke ether
Celligul Ewer bụ ihe juru ebe niile na eserese ndị dabeere na mmiri. Ha bụ isi ọrụ gụnyere:
Ihe mmetụta dị iche iche nwere ike ịmalite ntọala netwọkụ ugboro atọ site na ịmịkọrọ mmiri, si otú a na-abawanye vixopy na usoro owuwu nke agba ahụ.
Mmetụta nke nkwụchi ike: Cellilose e nwere ike igbochi nkụnye aka nke ụmụ irighiri ihe siri ike dị ka pigments na ndị depụtara na agba ma na-edozi otu agba ahụ.
Ihe onwunwe na-eme ihe nkiri: celligul ether nwekwara ike imetụta akụ na-akpụ akpụ nke agba ahụ, na-eme ka mkpuchi nwere ụfọdụ ihe siri ike na ịdị ogologo.
Enwere ọtụtụ ụdị mkpụrụ ndụ cellusuose, gụnyere methy cellulose (mc), hydroxyethyl methyl methyl, wdg. Ikike na nguzogide na mkpuchi.
2. Isi ihe kpatara esemokwu viscosise
N'oge nchekwa nke mkpuchi, mbelata vissity bụ ihe kpatara ihe ndị a:
(1) mwepu nke eyers cellugul
Mmetụta ndị dị omimi nke Ethers celluse na mkpuchi na-adabere n'ogo mmiri ha na iguzosi ike n'ezi ihe nke molular. N'oge nchekwa, ihe ndị dị ka okpomọkụ, acidity na alkalinity, na microorganisms nwere ike ibute ndị ekworo mkpụrụ osisi. Iji maa atụ, n'oge nchekwa oge ogologo oge acidic ma ọ bụ alkaline ma ọ bụ alkaline na mkpuchi ahụ nwere ike ịdị arọ nke cellulose eliducose nke cellulose na -eche ya, wee sikwa ike ya na ndagwurugwu.
(2) Nsogbu mmiri na mmiri mmiri
Sọgbọelu mmiri na-eme ka ọ dị ma ọ bụ njem mmiri na mkpuchi nwere ike imetụta ọnọdụ nke cellulose ether. N'oge nchekwa, akụkụ nke mmiri nwere ike ịba ụba ma ọ bụ mee ka ọ dị elu nke mkpuchi, na-eme ka nkesa mmiri na-enweghị isi, si otú a na-emetụta ogo cell na-eme ka mbelata na mpaghara mpaghara.
(3) microbial ọgụ
Uto microbial nwere ike ime na mkpuchi mgbe a na-echekwa ya ma ọ bụ na nchekwa na-abaghị uru. Microorganisms nwere ike ijikwa ndị na-eme ihe na ndị ọzọ dị iche iche, na-eme ka mmetụta ha na-emetụ ma na-eme ka vieing belata. Ahịhịa dakwasịrị mmiri, nke kachasị, bụ ezigbo gburugburu maka microbial uto n'ihi na ha nwere mmiri buru ibu.
(4) ka oke ikuku
N'okpuru ọnọdụ nchekwa okpomọkụ dị elu, nke anụ ahụ ma ọ bụ kemịkalụ nke cellulose e nwere ike ịgbanwe. Dịka ọmụmaatụ, usoro cellulose na-adịkarị mfe ma ọ bụ pyrolysis dị elu na okpomọkụ dị elu, na-ebute ike nke mmetụta ndị na-adịghị ike. Okpomoku di elu na-emekwa ka mmiri di iche na mmiri mmiri, na-enwewanye mmetuta nsogbu vicity.
3. Tozọ iji meziwanye nchekwa nke mkpuchi
Iji belata mbelata na viscosity n'oge nchekwa ma gbasaa ndụ nchekwa nke mkpuchi, enwere ike iwere ndụ nchekwa, enwere ike iwere usoro ndị a:
(1) na-ahọpụta ikike nke Ether
Eversdị dị iche iche nke eyers nwere ọrụ dị iche na usoro nchekwa nchekwa. Ethsgbọ elu cellugul na-enwe elu molecular dị elu nwere mmetụta dị mma nke ọma, mana ịchebe nchekwa ha bụ oke ibu nwere oke molecular nwere ike inwe arụmọrụ ka mma. Ya mere, mgbe ị na-echekwa usoro, a ga-ahọpụta usoro nke nwere ezigbo nchekwa nchekwa, ma ọ bụ nke eyers cellulase kwesịrị ijikwa ya na ndị ọzọ dịtụ iji meziwanye nguzogide ha.
(2) ịchịkwa pH nke mkpuchi
Acidity na alkalinity nke usoro mkpuchi nwere mmetụta dị mkpa na nkwụsi ike nke etters. Na usoro imewe, a ga-achịkwa uru nke mkpuchi ahụ iji zere gburugburu acidic ma ọ bụ gburugburu ebe obibi iji belata mmebi nke eyers cellushose. N'otu oge ahụ, ịgbakwunye ego kwesịrị ekwesị nke onye na-emegharị PH ma ọ bụ na-echekwa ihe nwere ike inye aka mee ka ph nke sistemụ ahụ.
(3) iwelie iji ihe eji eme ihe
Iji gbochie mmepụta microbial, a ga-agbakwunye ihe kwesịrị ekwesị na-akwado ya na mkpuchi. Ihe nchekwa nwere ike igbochi uto nke microorganisms, si otú ahụ gbochie ndị dị iche iche dịka celdilose ether ka ọ na-emebi emebi ma na-ejigide nkwụsi ike nke mkpuchi. Ekwesịrị ịhọrọ nchekwa kwesịrị ekwesị dabere na usoro nhazi ụlọ na ebe nchekwa, ọ ga-elele ịdịmma ha mgbe niile.
(4) ịchịkwa gburugburu ebe nchekwa
Ọnọdụ nchekwa na iru mmiri nke mkpuchi ahụ nwere mmetụta dị na ndakpọ olileanya viscositse. Ekwesịrị ịchekwa mkpuchi ahụ na gburugburu na ebe dị jụụ, na-ezere oke okpomọkụ na ọnọdụ iru mmiri dị elu iji belata mmebi nke na-emebi emebi na-emebi. Na mgbakwunye, ngwugwu ngwugwu nke ọma nwere ike belata ịkwaga na mmiri ma gbuo oge mbelata na viscosity.
4. Ihe ndị ọzọ na-emetụta viscosity
Na mgbakwunye na ebers cellulose, ihe ndị ọzọ dị na sistemụ mkpuchi nwekwara ike imetụta mgbanwe na viscosise. Iji maa atụ, ụdị na ntinye nke pigments, ọnụego sọks, yana ndakọrịta nke ndị ọzọ dị omimi nwere ike imetụta vicity nke mkpuchi. Ya mere, njiri mara nke usoro mkpuchi na njikọta n'etiti ihe mejupụtara bụ isi ihe dị mkpa iji lebara anya.
Ibelata viscosity n'oge ịchebe mkpuchi ahụ nwere njikọ chiri anya na ihe ndị a na-edebe ihe ubi, na-edozi window, na mmiri mmiri. Iji meziwanye nchekwa nke mkpuchi, ụdị kwesịrị ekwesị cellet dị iche iche, a ga-eme ka ph of e kwesịrị ịdị ike, a ga-eme ka usoro nchekwa ahụ sie ike. Site na njiri mara ezi uche na njikwa nchekwa, nsogbu nke viscositse, enwere ike belata arụmọrụ nke mkpuchi nke ọma, yana ọrụ nke ngwaahịa na nke ahịa a ga-aka mma.
