Uzinzo lwe-seluplose

Ukuzinza kwe-Selesese Telupese e-Telulose e-Eles libhekisa kubuchule babo bokugcina iipropathi zabo kunye nezomzimba ngokuhamba kwexesha, phantsi kweemeko ezahlukeneyo zokusingqongileyo kunye neeparamitha eziqhubayo. Nazi ezinye izinto eziphembelela uzinzo lwe-seluplose

1. I-Hydrolyction Izizi: I-Selessese Telupevey ichaphazeleka kwi-hydrolysis, ngakumbi phantsi kweemeko ze-acidic okanye i-alkaline. Ukuzinza kwe-seluplose ehafu kuphakama kwinqanaba labo lokufakelwa kwe (DS) kunye nenkqubo yemichiza. I-DS ephezulu ye-ds selsulose ensunt inyangeka kakhulu kwi-hydrolysis xa kuthelekiswa ne-DS ye-DS. Ukongeza, ubukho bamaqela akhuselayo afana ne-methyl, i -thyl, okanye amaqela e-hydroxypropy aphucula uzinzo lwe-hydrolycy lweseli.
2. Uzinzo lobushushu: I-Seleulose Talupe ibonise uzinzo oluhle nge-thermal phantsi kwenkqubo eqhelekileyo kunye neemeko zokugcina. Nangona kunjalo, ukuvezwa kwexesha elide kubushushu obuphakamileyo kunokukhokelela ekuthandeni, kukhokelela kutshintsho kwi-viscosity, ubunzima bemolekyuli, kunye nezinye iipropathi zomzimba. Ukuzinza kwe-shirmal ye-sellulose ehafu kuxhomekeke kwizinto ezinje ngezityholo zePolymer, ubunzima, kunye nobukho bokuzinzisa iiarhente zokuzinzisa.
3. I-PHIACES: I-Selessese edade zizinzile kuluhlu olubanzi lweenqobo ezibanzi ze-PH, ngokuqhelekileyo phakathi kwe-PH 3 nese-11. Nangona kunjalo, iimeko ze-PH zinokuchaphazela uzinzo kunye nokusebenza kwazo. Iimeko ze-acidic okanye i-alkaline zingakhokelela kwi-hydrolysis okanye ukonakaliswa kwe-seluplose enithi, kukhokelela ekuphulukaneni nokulahleka kobukhosi kunye neepropathi ezinkulu. Ifomula eneeselsese iintsapho kufuneka zenziwe kumanqanaba e-pH zikuluhlu lwe-polymer.
4. Uzinzo lwe-oxidass: I-Selese Telupe ichaphazeleka ekuthuthuzelweni kwe-oxidage xa ​​ityhilwe kwiiarhente zeoksijini okanye iiarhente ze-oxidifing. Oku kungenzeka ngexesha lokuqhutywa, ukugcinwa, okanye ukuveza umoya. I-Antioxidants okanye imihlaba yokuzinza inokongezwa kwifomu ye-ether yokuphucula uzinzo lwe-oxidative kunye nokuthintela ukonakaliswa.
5. Uzinzo olukhanyayo: I-Selessese i-Telulose Yizinzile ngokubanzi kukukhanya, kodwa ukuvezwa kwexesha elide kwi-iltraviolet (UV) kungakhokelela ekuthandeni nasekuphehleni. Izizwe ezikhanyayo okanye i-absissibers inokuthi ifakwe kwifomu equkethwe i-selsulose enyaweni ukuze inciphise iifoto zefoto kwaye zigcine uzinzo lwemveliso.
6. Ukuhambelana nezinye izithako: Ukuzinza kwe-Selese Teluplose Telupen kunokuphenjelelwa kukunxibelelana nezinye izithako kulungelelwaniso, ezinjengezinyibilikiswa, iityuwa, kunye nokongezwa. Uvavanyo lokuhambelana kufuneka lwenziwe ukuqinisekisa ukuba ii-Selessese ziye zihlala zizinzile kwaye azikwazi ukwenziwa ukwahlulwa kwesigaba, okanye ukuqina, okanye ezinye iziphumo ezingafunekiyo xa zidityaniswa nezinye izinto.

Ukuqinisekisa ukuzinza kwe-selulose e kanina kufuna ukukhetha ngononophelo kwezinto ezingafunekiyo, ukwenziwa kwenkqubo, iimeko ezifanelekileyo zokwenza, kunye nokugcina izinto ezifanelekileyo kunye nokuphatha. Abavelisi bahlala beqhuba uvavanyo lokuzinza ukuze kuvavanye intsebenzo kunye nobomi besherifu ye-ether-enemveliso eneemveliso phantsi kweemeko ezahlukeneyo.
