Iziphumo zepropathi yemveliso evela kwi-sellulose ether kwisicelo sodaka oluxubileyo

Njengoko eyona nto ibaluleke kakhulu ekwakheni iimveliso ezixubileyo ezixubileyo, i-sell sether idlala indima ephambili kwintsebenzo kunye neendleko zodaka oluxubileyo. Zimbini iintlobo zeselpulose Talupe: Inye i-iodic, ezinje nge-sodium yebhokisi ye-sodium, i-cmc), kunye ne-methyl ye-ionic, i-HCDROXYETHL (HPMC), njl . Ngokwanda kokuthandwa okukhulayo kokusetyenziswa kohlobo oluxubeneyo, ilizwe lam liya kuba ngumoya omkhulu wehlabathi wodaka oluxubileyo, ukusetyenziswa kwe-ilsulose i-Ether kuya kwandiswa ngakumbi. Intsebenzo yemveliso ye-selsulose ether kwi-purr oxutyweyo ixubekiweyo iba lujoliso lwabavelisi kunye nabasebenzisi.

Elona mpahla libalulekileyo le-seluplose i-ether kukugcinwa kwawo amanzi. Ngaphandle kongezwa kwe-selsulose ether, umaleko omncinci owomileyo owomileyo waphuma ngokukhawuleza ukuba isamente ayinakukhumbula ngendlela eqhelekileyo kunye nodaka alunakukhubaza. Kwangelo xesha, ukongezwa kwe-ether sete i-ete i-Eter yenza ukuba udaka luneplastiki elungileyo kunye nokuguquguquka, kwaye kuphucula amandla aphezulu kodaka. Makhe sithethe ngefuthe lokusebenzisa udaka oluxubileyo kwimveliso yemveliso ye-seluplose ether.

I-1. Ukulunga kweselphulose

Ukulunga kwe-Sete Ither ichaphazela ukuluka kwayo. Umzekelo, ukuthoba ubuhle be-seluplose i-ether, ngokukhawuleza kuyayinyibilika emanzini nasekuphuculeni ukusebenza kwendlela yokugcina amanzi. Ke ngoko, ukulunga kukaEterise Ertulose kufuneka kubendakanyiwe njengenye yeepropathi zayo zophando. Ngokubanzi, intsalela ye-SEEve ye-Selese Other toise dein i-0.212mm ayifanele ibe ngaphezulu kwe-8.0%.

2. Ukomisa inqanaba lokunciphisa umzimba

Ixabiso elomileyo lokunciphisa umzimba libhekisa kwipesenti yobunzima bezinto ezilahlekileyo kubunzima besampulu yentsusa xa i-Selese i-Ether yomiswe kubushushu obuthile. Kumgangatho othile we-eruplose Ether, inqanaba lokunciphisa umzimba liphezulu kakhulu, eliza kunciphisa umxholo wezithako ezisebenzayo kwi-Telulose Ether Mericas, kwaye inyuse iindleko zokuthenga. Ngokwesiqhelo, ilahleko yobunzima ekuyomiseni i-ether sether ayiphezulu kwe-6.0%.

I-3. I-Ash ye-Ashe yomxholo weSeluplose Ether

Kumgangatho othile we-seluplose i-ether, umxholo we-Ash uphakame kakhulu, oya kunciphisa umxholo izithako ezisebenzayo kwi-Telulose Ether kwaye uchaphazele isiphumo semisebenzi yesicelo. Umxholo we-ash ye-ash ye-seluplose i-ether ngumlinganiso obalulekileyo wokusebenza kwayo. Idityaniswe nemeko yangoku yemveliso yelizwe lethu le-Ish Sether, idla ngokuba yi-MC, i-HPMC, i-HMMC ayifanele idlule kwi-2,5% ye-hec sete ye-hec set.

I-4. I-Vilosity ye-Selese-Iter

Isiphumo samanzi kunye nesiphumo esihlekisayo se-ether iselutase ikakhulu ixhomekeke kwi-viscofity kunye nedosi ye-selsulose i-ether ngokwayo yongezwa kwi-cerry.

I-5. Ixabiso le-p ye-seluplose ether

I-viscosity ye-Ether ye-Ether I-Ether I-Eler I-Eler iya kuncitshiswa emva kokuba igcinwe kubushushu obuphezulu okanye ixesha elide, ngakumbi kwiimveliso ze-viscofity ephezulu, ke kufuneka ukunciphisa umda kwi-PH. Ngokubanzi, kuyacetyiswa ukuba ulawule i-PH ye-PH I-Teluplose Ether ukuya kwi-5-9.

I-6. Ukukhanya kokukhanya kweSelsulose Ether

Ukukhanya okugqithisileyo kwe-selsese i-Ether ichaphazela ukwenziwa kwayo isicelo kwizinto zokwakha. Ezona zinto ziphambili ezichaphazela ukukhanya okukhanyisa i-Telulose Ethe: (1) Umgangatho wezinto ezingafunekiyo; (2) Iziphumo ze-alkalition; (3) Inqanaba lenkqubo; (4) Umyinge weSolvent; (5) Iziphumo zokungathathi cala. Ngokwesiphumo sokusetyenziswa, ukhanyiso ukutshintshwa kwe-ertulose ether akufuneki kungabi ngaphantsi kwe-80%.

7. Iqondo lokushisa le-gelsulose ether

I-Teluplose Ether isetyenziswa ikakhulu njenge-viscosifier, iarhente yokugcina amanzi kwiimveliso zesamente, ke i-viscosity kunye neqondo lobushushu le-gel zizinto ezibalulekileyo zokuphawula i-Telulose Ether. Iqondo lokushisa le-gel lisetyenziselwa ukumisela uhlobo lwe-seluplose ether, enxulumene nenqanaba lokufakwa kwenye i-selulose. Ukongeza, ityiwa kunye nokungcola kunokuchaphazela iqondo lobushushu le-gene. Xa ubushushu besisombululo buyanyuka, i-sellyuse polymer ngokuthe ngcembe iphulukana namanzi, kwaye i-viscosity yesisombululo iyancipha. Xa inqaku lejeli lifikelelwe, i-polymer ikhuphe ngokupheleleyo kwaye iyenza ijeli. Ke ngoko, kwiimveliso zesamente, ubushushu buhlala bulawulwa ngezantsi kweqondo lobushushu. Ngaphantsi kwale meko, iqondo lobushushu, ukuphakama kwe-viscofity, kunye nokubonakalayo ngakumbi kokutsalwa kwamanzi kunye nokugcinwa kwamanzi.
