Okwangoku, umgangatho we-hydropyl ye-hythylcelcelceluplose yahluka kakhulu, kwaye ixabiso liyahluka kakhulu, lenza kube nzima kubathengi ukuba benze ukhetho olufanelekileyo. I-HPMC eguqulweyo yenkampani enye yelinye ilizwe sisiphumo seminyaka emininzi yophando. Ukongezwa kwezinto zolandelelo kunokuphucula ukusebenza nokuphucula ukusebenza. Ewe kunjalo, iya kuchaphazela ezinye iipropathi, kodwa ngokuthetha ngokubanzi; Inye kuphela injongo yokongeza ezinye izithako kukunciphisa iindleko, kubangele ukuncitshiswa kwamanzi okunciphisa amanzi, ukubekwa kunye nezinye iipropathi zemveliso, okukhokelela kwiingxaki ezininzi ezisemgangathweni.
Kukho umahluko phakathi kokwahluka phakathi kwe-HPMC ecocekileyo kunye ne-HPMC edumileyo:
I-1. I-HPMC ecocekileyo ibonakale i-fluffy kwaye inesixa se-bulf esiphantsi, sisuka kwi-0.3-0.4G / ML; I-HPMCTECTIONCTIONCE inolwelo olungcono kwaye ivakale inzima, oko ngokucacileyo kwahlukile kwimveliso yokwenene ngembonakalo.
I-2. Isisombululo esisulungekileyo se-HPMC sicacile, ukuguqula okuphezulu okuphezulu, kunye nenqanaba lokugcina amanzi ≥ 97%; Isisombululo se-HPMC esibonisa ukuba sinamafu, kwaye izinga lokugcina amanzi kunzima ukufikelela kwi-80%.
3. I-HPMC ecocekileyo ayifanele ivule i-ammonia, isitatshi kunye notywala; I-HPMCRECTIONCTE i-HPMC inokuchitha zonke iintlobo zevumba, nokuba ayinantsingiselo, iya kuziva inzima.
I-4. I-HPMC ecocekileyo ye-HPMC i-fibrous phantsi kwemakroskopu okanye iglasi yokukhulisa; I-HPMCRECTIONCTURTEDC inokubonwa njengezinyibilikisi zegralini okanye amakristali phantsi kwe-microscope okanye iglasi yokukhulisa.
Ukuphakama okungapheliyo kwe-200,000?
Uninzi lweengcali zasekhaya kunye nabaphengululi bapapashe amaphepha akholelwa ukuba ukuveliswa kwe-HPMC kuthintelwe ngokhuseleko lwasekhaya kunye nokutywina, iinkqubo zoxinzelelo ezingenako ukuvelisa iimveliso nge-viscosity engaphezulu kwe-200,000. Ehlotyeni, akunakwenzeka ukuba uvelise iimveliso nge-viscosity engaphezulu kwe-80,000. Bakholelwa ukuba iimveliso ezibizwa ngokuba zingama-200,000 kufuneka zibe ziimveliso ezingeyonyani.
Iingcali zengcali azinangqondo. Ngokwemeko yangaphambili yemveliso yemveliso, ezi zigqibo zisentla zinokutsalwa okunene.
Eyona nto iphambili yokwandisa i-HPMC kukutywina okuphezulu kwe-reactor kunye nokuphendula okuphezulu kunye nezinto eziphezulu eziphezulu. Umoya ophakamileyo womoya uthintela ukonakaliswa kweselselose ngeoksijini, kwaye imeko yokuphendula eyona ngcinezelo ikhuthaza ukungena kwe-elektrone kwi-sellsulose kwaye iqinisekisa ukufana kwemveliso.
Isalathiso esisisiseko se-200000cps hydroxypropyl methylcelcelcelcelcelcelceluplose:
I-2% ye-ACTEACEOR YOKUGQIBELA I-200000cps
Imveliso icocekile ≥98%
Umxholo we-APENKA 19-24%
Umxholo weHydroxypropoxy Umxholo: 4-12%
I-200000cps hydroxdpropyl methylcelcelces:
I-1. Ukugcinwa kwamanzi ngokugqibeleleyo kunye neepropathi ezinkulu zokuqinisekisa ukuba i-hydication epheleleyo yesilayidi.
I-2. Ukuxhobisa amandla aphezulu kunye nefuthe elibonakalayo lomoya, ukuthintela i-shrinkage kunye nokuqhekeka.
3. Ukulibazisa ukukhutshwa kwe-qument hydration, kulibazisa ixesha, kwaye ulawule ixesha elihlekisayo lodaka lwesamente.
4. Ukuphucula ukungangqinelani kwamanzi kodaka oluhleweyo, ukuphucula i-RUOOLOGLO, kunye nokuthintela ukwahlula kunye nokopha.
5. Iimveliso ezizodwa, ezijolise kwindawo yokwakha amaqondo obushushu ehlotyeni, ukuqinisekisa ubushushu obufanelekileyo bokutyibilika ngaphandle kokwazisa.
Ngenxa yokubekwa esweni kwentengiso ye-LEX, ukhuphiswano kwishishini lodaka luya luhlala lushushu. Ukwenzela ukulungiselela ukuthengisa, abanye abathengisi baxuba inani elikhulu lezinto eziphantsi kwexabiso eliphantsi ukuvelisa i-ether ishibhile. Apha, umhleli unyanzelekile ukuba akhumbuze abathengi abangaboniyo ukuba basebenzise amaxabiso aphantsi, ukuze bangakhohliswa, khokela kwiingozi zobunjineli, kwaye ekugqibeleni kuyayila ilahleko.
Iindlela eziqhelekileyo zokuThelelwa kunye neendlela zokuchonga:
.
Indlela yokuchonga: Ngenxa yeempawu ze-Amissies, olu hlobo lwesisombululo se-selsulose ihlala inombala we-phenomeno, kodwa i-selupese elungileyo ayiyi kuvela i-phenomenon, isisombululo esifana ne-jelly, sitsalwa.
(2) Yongeza isitatshi kwi-seluplose ether. Isitatshi ngokubanzi singanyibilikisi emanzini, kwaye isisombululo sihlala sidlulisela ukukhanya.
Indlela yokuchonga: Drop Iscose Eler I-I-I-I-I-I-IODIINE YAYONO, ukuba umbala ujika uluhlaza, inokuqwalaselwa ukuba isitatshi songezwa.
(3) Yongeza i-polyviny i-powder yotywala. Njengoko sonke sazi, ixabiso lentengiso le-polyvinyl powder enje nge-2488 kwaye i-1788 ihlala isezantsi kuneso selupeble i-ether inokuthi inciphise indleko ze-iluplose.
Indlela yokuchonga: Olu hlobo lwe-ether yeselselose ihlala i-granular kwaye inomsindo. Inyibilikisa ngokukhawuleza ngamanzi, khetha isisombululo ngeglasi yeglasi, kuya kubakho into ebonakalayo ebonakalayo.
ISISHWANKATHELO: Ngenxa yesakhiwo esikhethekileyo kunye namaqela, ukugcinwa kwamanzi kwe-ether ye-seluplose akunakutshintshwa zezinye izinto. Nokuba loluphi uhlobo lwe-filler luxutywe ngaphakathi, lo gama nje ixutywe kwisixa esikhulu, ukugcinwa kwamanzi kwalo kuya kuncitshiswa kakhulu. Isixa se-HPMC esine-viscofity eqhelekileyo ye-10w kudaka oluqhelekileyo yi-0.15 ~ 0.2 ‰, kunye nexabiso lokugcina amanzi le> 88%. Ukopha kunzulu kakhulu. Ke ngoko, inqanaba lokugcinwa kwamanzi luyinto ebalulekileyo ukulinganisa umgangatho we-HPMC, nokuba ilungile okanye imbi, lo gama ivelisiwe kodaka, iya kucaca xa ijonga.
