Isingeniso:
Izikhangiso ezisuselwa kwaLatex zisetshenziswa kabanzi emikhakheni ehlukahlukene ngenxa yokusebenza kokuhlukahlukene, amandla abopha, kanye nobungane bezemvelo. Lezi zinamathela ziqukethe ukuhlakazwa kwezinhlayiya ze-polymer emanzini, nge-latex ibe yingxenye eyinhloko. Kodwa-ke, ukuthuthukisa ukusebenza kwazo futhi kuhambisane nezicelo ezithile, izithasiselo ezahlukahlukene zifakwa ezakhiweni ezinamathela nge-latex. Phakathi kwalezi zengezo, izithambiso ze-cellulose zidlala indima ebalulekile, edlulisela izakhiwo ezifiselekayo njengokulawulwa kwe-viscosity, ukugcinwa kwamanzi, nokutholwa kokunamathela.
Izakhiwo ze-cellulose afesther:
I-Cellulose I-Teshers iyi-derivatives of cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. Zitholakala ngokuguqula amakhemikhali ngokushintshana ngokungezwani. Izinhlobo ezivame kakhulu ze-cellulose izithathi ezisetshenziswa ezinama-adhesives ezisuselwa kwangaphansi zifaka i-methyl cellulose (MC), i-hydroxyyethyl cellulose (HPCHPROPYL Cellulose (HPC). Uhlobo ngalunye lubonisa izakhiwo ezihlukile ezinikela ekusebenzeni kwama-adhesives asuselwa ku-latex.
Ukulawulwa Kwe-Viscosity:
Eminye yemisebenzi eyinhloko ye-Cellulose I-Adhesives esekelwe kwaTatex iyisilawuli se-Viscosity. Ukungezwa kwezithambekela ze-cellulose kusiza ukulungisa i-viscosity yokwakhiwa okunamathelayo, okwenza kube lula ukuphatha futhi kusebenze. Ngokuguqula i-viscosity, ama-cellulose, anika amandla ukulawula okuqondile kokugeleza nokusakaza izakhiwo zokunamathela, ukuqinisekisa ukumbozwa okufanayo kanye namandla obopho.
Ukugcinwa kwamanzi:
I-Cellulose I-Teshers yi-Hydrophilic polymers ekwazi ukuheha nokugcina ama-molecule amanzi. Kuzinhlelo zokusebenza ezinamathela okususelwa ku-Latex, le mpahla iyazuzisa kakhulu njengoba ithuthukisa isikhathi esivulekile sokunamathela - isikhathi lapho ukunamathela kuhlala khona ngemuva kwesicelo. Ngokubambezela inqubo yokumisa, i-cellulose i-tefers yandisa iwindi lokuma kahle nokulungiswa kwezingane ezihlanganisiwe, ngaleyo ndlela kusiza izibopho ezinamandla nezinokwethenjelwa.
Ukuthuthukiswa kokunamathela:
AbakwaCellulose Abathambekele futhi banikela ekusebenzeni kokunamathela kokunamathelayo ngokukhuthaza ukusebenzisana kwezinto ezinamathela phakathi kwezindawo ezinamathela kanye nezindawo ezingaphansi komhlaba. Nge-hydrogen bonding nezinye izindlela, ama-cellulose asher athuthukisa ukumazi kanye nokunamathela ku-substrates ahlukahlukene, kufaka phakathi izinkuni, iphepha, izindwangu kanye ne-ceramics. Lokhu kuphumela emandleni e-bond athuthukisiwe, ukuqina, kanye nokumelana nezici zezemvelo ezifana nokuguquguquka komswakama nokushisa kwezinga lokushisa.
Ukuvumelana ne-Latex Polymers:
Enye inzuzo esemqoka ye-cellulose afers ukuhambisana kwawo nge-latex polymers. Ngenxa yemvelo yabo efanayo ye-hydrophilic, ama-cellulose iziphotha asabalalisa ngokufana ekusakazweni kwe-latex ngaphandle kokuthinta izinzwa zazo noma izimbongolo. Lokhu kuvumelana kuqinisekisa ukusatshalaliswa kwezengezo kwezengezo kulo lonke i-matrix enamathela, okwenza kube lula ukusebenza futhi kunciphise ukungahambisani nokwakheka.
Ukusimama Kwezemvelo:
AbakwaCellulose Abapholi batholakala kwizinsizakusebenza ezivuselelekayo, benza ukuba babezengezelele izithasiselo zemvelo zokunamathela okususelwa ku-latex. Ngokungafani nama-polymers okwenziwa, asuselwa kuma-petrochemicals, ama-cellulose afers ayi-biodegradable futhi abeke umthelela omncane emvelo. Njengoba isidingo sezixazululo ezinama-adhesive anama-adhesive sikhula, abathengisi be-cellulose banikela ngenye indlela yokuphoqelela abakhiqizi abafuna ukunciphisa ukunciphisa izinyathelo zekhabhoni yabo futhi bathobele imithethonqubo yokusimama.
Isiphetho:
AbakwaCellulose Abapholile badlala indima ebalulekile ekuthuthukiseni ukusebenza kwezithasiselo ezisuselwa kwangaphansi kwezicelo ezahlukahlukene. Ukusuka ekulawuleni kwe-Viscosity nokugcinwa kwamanzi ekuthuthukisweni kokunamathela kanye nokusimama kwemvelo, abapholisi be-cellulose banikela ngezinzuzo eziyiminyene ezinomthelela ekwakhekeni nasekusebenzeni kwalezi zinama ezinamathekisi. Njengoba izimboni ziyaqhubeka nokusungula futhi zifune ezinye izindlela eziluhlaza okotshani, izipho ze-cellulose zilungele ukuhlala izithasiselo ezihlanganisiwe ekuthuthukisweni kwezixazululo ezinama-adhesive ezilandelayo.
