Ngawaphi amanyathelo okuthintela ukulinganisa i-viscosity ye-hydroxypropyl methyl celluloseHPMC?Xa sivavanya i-viscosity ye-cellulose.Ukwenzela ukuqinisekisa ukuchaneka kweziphumo zovavanyo, ingqwalasela eyodwa kufuneka ihlawulwe kule miba mine ilandelayo.
1. Izalathi zentsebenzo zesixhobo mazihlangabezane neemfuno zemimiselo yesizwe yoqinisekiso lwemitha yemitha.
Ii-hydroxypropyl methyl celluloseIsixhobo sokulinganisa i-viscosity sisetyenziswa kumjikelo wovavanyo.Ukuba kuyimfuneko (isixhobo sisetyenziswa rhoqo okanye kwisimo esibalulekileyo sokufaneleka), uvavanyo oluphakathi lwenziwa ukuze kuqinisekiswe ukuba ukusebenza komlinganiselo ufanelekile kwaye impazamo ye-coefficient ingaphakathi kuluhlu oluvumelekileyo, ngaphandle koko idatha echanekileyo ayinakufunyanwa.
2. Nika ingqalelo ekhethekileyo kubushushu bolwelo olulinganiswayo.
Abasebenzisi abaninzi bayayihoya le nto kwaye bacinga ukuba iqondo lokushisa liphantse lingabalulekanga.Imifuniselo yethu ibonisa ukuba: xa ukutenxa kobushushu kuyi-0.5℃, ukutenxa kwe-viscosity kolunye ulwelo kungaphezulu kwe-5%.Ukuphambuka kweqondo lokushisa kunempembelelo enkulu kwi-viscosity, iqondo lokushisa kunye ne-viscosity.Ke ngoko, kufuneka kuthathelwe ingqalelo ekhethekileyo ukugcina ubushushu bolwelo olulinganisiweyo kufutshane neqondo lokushisa elichaziweyo, kwaye ukulinganisa ngokuchanekileyo, kungcono ukuba ungadluli kwi-0.1℃.
3. Ukukhethwa kwesitya sokulinganisa (ityhubhu yangaphandle).
Kwimibhobho emibini ye-viscometers ejikelezayo, funda incwadana yesixhobo ngokucophelela kwaye ufanise i-rotor (i-cylinder yangaphakathi) ngokufanelekileyo.I-cylinder yangaphandle, ngaphandle koko iziphumo zokulinganisa ziya kuphambuka kakhulu.Kwi-viscometer eyodwa ye-cylinder rotational, i-radius ye-cylinder yangaphandle kufuneka ibe yinto engapheliyo kumgaqo.Umlinganiselo wangempela ufuna ukuba i-diameter yangaphakathi ye-cylinder yangaphandle ayikho ngaphantsi kobukhulu obuthile.Ngokomzekelo, i-viscometer ye-rotary ye-NDJ-1 idinga i-beaker yokulinganisa okanye isitya setyhubhu esithe ngqo esingekho ngaphantsi kwe-70 mm ububanzi.Iimvavanyo zibonise ukuba iimpazamo ezinkulu zokulinganisa zingabangela ukuba ububanzi bangaphakathi bomkhumbi buncinci kakhulu, ngakumbi xa i-rotor no.I-1 isetyenzisiwe.
I-4, ngokuchanekileyo ukhethe i-rotor okanye ulungise isantya, ukwenzela ukuba ixabiso legridi yamandla phakathi kwe-20-90.
Olu hlobo lwesixhobo lusebenzisa i-dial plus pointer readings, kwaye indibaniselwano yokuzinza kunye nokutenxa kokufunda kuneegridi eziyi-0.5.Ukuba ukufundwa kuncinci kakhulu, kusondela kwiigridi ezi-5, impazamo ehambelanayo ingaba ngaphezu kwe-10%.Ukuba i-rotor echanekileyo ikhethiweyo okanye ukufundwa kwesantya ngama-50, impazamo ehambelanayo ingancitshiswa ibe yi-1%.Ukuba ixabiso libonisa ngaphezu kwe-90, i-torque eveliswa yintwasahlobo inkulu kakhulu, ekulungele ukukhahlela kunye nokonakalisa i-hairspring, ngoko kufuneka sikhethe ngokuchanekileyo i-rotor kunye nesantya.
Eli phepha lazisa imiba efuna ingqalelo ekulinganiseni i-viscosity ye-hydroxypropyl methyl cellulose, ngethemba lokuba lo mxholo ungasentla unokukunceda ukuvavanya.KIMA CHEMICALibambelela kumgaqo "wokutsha, umthengi kuqala, umgangatho kuqala".Ingqikelelo yophuhliso lweshishini kukwakha kwintembeko yexesha elide kunye nophuhliso, rhoqo ukusungula izixhobo kunye nobuchwepheshe, ukukhuselwa kokusingqongileyo okuluhlaza kunye nophuhliso lobuchwepheshe obuphezulu.Inkampani izimisele ukusebenzisana kunye neemveliso zasekhaya nezangaphandle ezikumgangatho ophezulu kunye nabahlobo ixesha elide, intsebenziswano enyanisekileyo.
