Qaphela:Iziphumo zomxholo owahlukileyo we-Hydroxypropyl Methylcelcelgalose Other kwipropathi yodaka oluxubileyo oxutywe ngokuxubileyo. Iziphumo zibonise ukuba: ngokunyuka komxholo we-Teluplose Ether, ukuguquguquka kunye nokuxineka kunciphile, nexesha lokumiswa kwehla. Ulwandiso, i-7D kunye nama-28D angama-28D unciphile, kodwa ukusebenza ngokutsha kodaka oluxubeneyo kuphuculwe.
0.Oolungiswa
Ngo-2007, ukugunyaziswa kwemithandathu kunye neemilori zelizwe zakhupha "isaziso sokuthintela ukudityaniswa kwesithuba sodaka kwezinye izixeko ngaphakathi kweminye imiqobo". Okwangoku, izixeko ezili-127 kwilizwe liphela ziye zenza umsebenzi othi "ntela "udaka olungenakwenziwa ngaphambili kuphuhliso lodaka oluxubileyo. ithuba. Ngophuhliso oluqinileyo lodaka oluxubileyo kwimarike yokwakha yasekhaya nezangaphandle Uphuhliso olusempilweni nocwangco. Okwangoku, njengekhonkrithi yekhonkrithi, imixokelelwane yomxube ongumxube isetyenziswa ikakhulu ngokudibeneyo, kwaye bambalwa basetyenziswa bodwa. Ngokukodwa, kukho uninzi lweentlobo zezifaniso ezidityanisiweyo ezidityanisiweyo, kodwa kunodaka oluqhelekileyo oluxubeneyo, akukho mfuneko yokuba ulandele inani lezinto ezibunjiweyo, ukuphepha inkunkuma engafanelekanga, kwaye uchaphazele umgangatho weprojekthi. Kubuqhetseba obuqhelekileyo obuxubeneyo, i-selupelose Ether idlala indima yokugcina amanzi, ukuqina, kunye nokuphuculwa kokusebenza kokwakhiwa. Umsebenzi wokugcina amanzi kakuhle uqinisekisa ukuba udaka oluxubeneyo aluyi kubangela isanti, isikhonkwane kunye nokuncitshiswa kwamandla ngenxa yokunqongophala kwamanzi kunye nokungapheleli kwamanzi; Iziphumo zokutyibilika ziphucula kakhulu amandla olwakhiwo lodaka olumanzi. Eli phepha lenza isifundo esicwangcisiweyo kwisicelo se-selsulose ether kwi-farring eqhelekileyo exutywe, ekhokelela kwindlela yokusebenzisa ubungqingqwa obuqhelekileyo obuxubeneyo.
I-1. Izinto ezingafunekiyo kunye neendlela ezisetyenziswayo kuvavanyo
1.1 Izinto ezingafunekiyo zovavanyo
Isamente yayingu-P. 042.5 yesamente, impukane ye-ish yeklasi isuka kwisityalo samandla eTaiyuan, i-Easter Sport i-5 mm okanye i-Eterase Ether i-GATYLYL ye-Ether (i-viscosity ye-12000 ye-12000).
1.2 Indlela yovavanyo
Ukulungiswa kwesampulu kunye novavanyo lwentsebenzo kwenziwa ngokwe-JCJ / T 70-2009 indlela yokusebenza yokuSebenza yokwakha umdaka.
2. Isicwangciso sovavanyo
2.1 ifomula yovavanyo
Kolu vavanyo, isixa sezinto ngasinye ezikrwada ezi-1 zodaka oluxubileyo oluxubeneyo zisetyenziswa njengefomula esisiseko yovavanyo, kwaye amanzi kukusebenzisa amanzi kwitoni enye yomxube.
2.2 Isicwangciso esithile
Sebenzisa le fomula, isixa se-hydroxypropyl methylcelcelcelse i-ersen orn ye-farting fake itreyitha ye-fastropyl methylcelselee emanzini Ukugcinwa, ukungqinelana, ukubeka ixesha, kunye namandla oxinzelelo okuxubeneyo, ukwenzela ukuba izibonelelo ezixubileyo ezixubileyo zinokuqonda ngokwenene ukusetyenziswa kwenkqubo yokuhlela, ukukhusela okusingqongileyo kunye nokugcinwa kwamandla.
3. Iziphumo zovavanyo kunye nohlalutyo
3.1 Iziphumo zovavanyo
Iziphumo zemithamo eyahlukeneyo ye-hydropylcelcelgalose ether kwindawo yokugcina amanzi, ukungqinelana, ukubonakala okubonakalayo, ukuseta ixesha lokuqhekeka okuxubeneyo.
3.2 Uhlalutyo lweziphumo
Ingabonwa kwifuthe leedosi ezahlukeneyo ze-hydropylcelcelgalose ether kwindawo yokugcina amanzi, ukungqinelana, ukubeka ixesha, kunye nodaka oluqhelekileyo lokudakumba okuxubeneyo. Ngokwanda kwe-Selese I-EEET, inqanaba lokugcina amanzi lodaka olumanzi likhula, ukusuka kwi-86.2% xa i-Hydroxyl Ityl Selelopyl Methyl Galoulose ixutywe. Ixabiso lokugcina amanzi lifikelela kwi-96.3%, engqina ukuba imiphumo yokugcina amanzi kwi-propyl methyl sete ihle kakhulu; Ukungqinelana ngokuthe ngcembe kuyancipha phantsi komsebenzi wokugcinwa kwamanzi we-propyl methyl sether ye-ether (ukusela kwamanzi kwitoni yomlinganiso); Ukuxinana okubonakalayo kubonisa indlela esezantsi, ebonisa ukuba imiphumo yokugcina amanzi ye-propyl methyl sether inyusa umthamo wodaka lwamanzi kwaye inciphisa ukuxinana; Ukuseta ixesha ngokuthe ngcembe kusondela ngokunyuka komxholo we-hydroxyl metyl sether, kunye nomxholo we-HydroxlyPOse I-ETERE i-ETERE i-ETER i-ETER yexesha lokurhweba; Amandla engcinezelo ye-7D kwaye i-28D inciphile (idosi enkulu, eyona nto ibonakalayo). Oku kuhambelana nokwanda kwevolumu yodaka kunye nokwehla kwi-vernity ebonakalayo. Ukongezwa kwe-hydroxypropyl methyl selethe i-Ethen inokwenza i-cevity evaliweyo ngaphakathi koHlala olulukhuni ngexesha lokubeka kunye nokukhuseleka kodaka. I-microporers iphucula ukuqina kodaka.
4. Amanyathelo okhuseleko kwisicelo se-selsulose ether kwi-purr eqhelekileyo exutywe
I-1) Ukukhetha kweemveliso ze-sell sete Ngokubanzi, kokukhona i-viscosity ye-vilelose ether, ilunge ngakumbi i-vission yokugcina amanzi, kodwa iphakame kakhulu, iphantsi kakhulu, iyonakalisa ukusebenza kwayo nokusebenza kodaka; Ukulunga kwe-ete yeseluplose i-Ertuse iphantsi kudaka oluqhelekileyo. Kutshiwo ukuba igqibele, kuya kuba lula ukuyinyibilikisa. Ngaphantsi komthamo ofanayo, ukulungisa ubuhle, kungcono umphumo wokugcina amanzi.
2) Ukukhetha i-selsulose ether dosage. Ukusuka kwiziphumo zovavanyo kunye nohlalutyo lwesiqulatho se-seluplose ekrwenqeni ukuntywila okuxubeneyo, kunokubonwa kwi-Eterase Ether, engcono, kuya kufuneka kuthathelwe ingqalelo kwimozulu ye-Teluphu, ifanelekile ukuba inyule i-dosage efanelekileyo. Umthamo we-hydroxypropyl methyl sethes ithe thessing of thespur exutyweyo kukukhetha i-0.1 kg / t-0.. Ingozi esemgangathweni; Umthamo we-hydroxypropyl methyl sethel sether kwi-fake-rack ecikizekileyo yedrafti engekhoyo malunga ne-3 kg / t.
I-3) Ukusetyenziswa kwe-selsulose ether kudaka oluqhelekileyo oluxubeneyo. Kwinkqubo yokulungiselela udaka oluqhelekileyo oluxubeneyo, isixa esifanelekileyo somxholo onokuthi wongeze, ngokukhethekileyo kwifuthe elithile lokugcina amanzi kunye nefuthe elihle, ukuze ikwazi ukwenza iindleko ze-talsulose, kwaye zigcine izixhobo; ukuba isetyenziselwe i-seluplose i-ether, amandla axhonyiweyo akanakukwazi ukuhlangabezana neemfuno, kwaye isixa esifanelekileyo se-Latex ye-Latex ye-Latex enokuphinda yongezwa; Ngenxa yexabiso eliphantsi lodaka, impazamo yomlinganiso inkulu xa isetyenziswa yedwa. Umgangatho weemveliso ezixubileyo ezixubileyo.
5. Izigqibo kunye neengcebiso
1) Kubuqhetseba obuqhelekileyo obuxubeneyo, ngenxa yokwanda komxholo we-hydroxypropyl methylcelsulose i-ether, ireyithi yokugcina amanzi ingafikelela kwi-96.3, ukungqinelana kunye nexesha ixesha elide lincitshisiwe. Amandla oxinzelelo ancitshiswa, kodwa umsebenzi ovuthayo wodaka oxubeneyo waphuculwa xa umxholo we-hydropyl methyl sether i-ethe mopicose i-ethe ye-methyl sether ithole i-Ether.
2) Kwinkqubo yokulungiselela ubuthongo obuqhelekileyo obuxubeneyo, i-Selese-I-Selete Ether enobuso obufanelekileyo kunye nokulunga kuya kukhethwa, kwaye idosi yayo kufuneka igqitywe ngokungqongqo ngovavanyo. Ngenxa yexabiso eliphantsi lodaka, impazamo yomlinganiso inkulu xa isetyenziswa yedwa. Kucetyiswa ukuba udibane nomphathi wokuqala wokuqala, kwaye emva koko unyuse isixa songezwa ukuqinisekisa ukuba umgangatho weemveliso ezixubileyo ezixubileyo.
3) Ubukho bodaka oluxubeneyo yishishini elikhulayo eTshayina. Kwinkqubo yokusebenzisa ububele, kufuneka singahambi kakuhle ubungakanani, kodwa sithathele ingqalelo umgangatho kunye nokunciphisa iindleko zokuveliswa, ukukhuthaza ukusetyenziswa kwentsalela yenkunkuma yemveliso, kunye nokufezekisa amandla okonga kwamandla kunye nokusetyenziswa kwamandla.
