Ukucoceka kwe-Hydroxypropyl Methylceluplose ekwakheni i-Nord kunye ne-Poketter ichaphazela ngokuthe ngqo umgangatho wolwakhiwo lwezobunjineli, yintoni le echaphazela ubunyulu be-hydylcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelcelil methylcelsele? Makhe ndiphendule lo mbuzo.
Kwinkqubo yemveliso ye-hydroxypropyl methylcelceluplose, ioksijini yentsalela kwindawo ye-HydroxyPropyl Methylcelcel ilinganiselwe, kodwa ioksijini ye-molergen ilinganiselwe kakhulu. Eyona nqanaba libalulekileyo lokuqinana kwamanzi lininzi ekufuneka lenzile ngomxholo we-hydroxylpyl. Ezinye zeefektri zifuna ukunciphisa iindleko kunye nexabiso, kodwa azifuni ukwandisa umxholo we-hydroxypropy, ngoko ke umgangatho awukwazi ukufikelela kwinqanaba lemveliso yangaphandle efanayo.
Iqondo lokugcina amanzi le-hydroxypropyl methylcelgalose ikwanobudlelwane obukhulu kunye ne-hydroxypropy, kunye nenkqubo yonke yokuphendula, i-HydroxyPOpy ikwamisela inqanaba lokugcina amanzi Iziphumo zokwenza i-alkalization, umyinge we-methyl chloride kwaye i-proplone oxide, uxinzelelo lwe-Alkali kunye nomlinganiselo wamanzi kwikotoni ehlaziyiweyo yonke i-cotton ichaza ukusebenza kwemveliso.
Umgangatho wezinto ezingafunekiyo, isiphumo se-alkalization, ulawulo lwenkqubo yenkqubo, umyinge wemizila kunye nefuthe lokungathathi cala imisela ukunyibilika emva koko, yayilifu njengokwakho Ubisi, abanye babemhlophe, abanye babetyheli, kwaye abanye babecacile kwaye becacile. Ukuba ufuna ukuyicombulula, uhlengahlengise kwezi zinto zingasentla. Ngamanye amaxesha i-acetic acid inokuchaphazela kakhulu ukuhambisa ukukhanya. Kungcono ukusebenzisa i-acetic acid emva kodumo. Eyona mpembelelo inkulu kukuba i-rating inomdla kwaye nokuba ngaba inkqubo iyazinza (ezinye izinto zinokuziswa komswakama kwaye njengokurinta). Ngapha koko, uninzi lwezinto ziya kudlala. Ngokuzimela kwezixhobo kunye nokusebenza kwabaqhubi abaqeqeshelwe kakuhle, iimveliso ezivelisiweyo kufuneka zizinzile kakhulu. Ukukhanya kokukhanya akuyi kudlula kuluhlu lwe-2%, kunye nokufakwa endaweni yamaqela athatyathwayo kufuneka alawule kakuhle. Endaweni yokufana, ukuqaqamba kokukhanya kuya kuba kulungile.
