Ke litemoso life tsa ho lekanya viscosity ea hydroxypropyl methyl cellulose?HPMC?Ha re hlahloba viscosity ea cellulose.E le ho netefatsa ho nepahala ha liphetho tsa liteko, tlhokomelo e khethehileng e lokela ho lefshoa likarolong tse 'nè tse latelang.
1. Matšoao a ts'ebetso ea sesebelisoa a tlameha ho fihlela litlhoko tsa melaoana ea naha ea netefatso ea metroloji.
Thehydroxypropyl methyl celluloseSesebelisoa sa ho lekanya viscosity se sebelisoa potolohong ea liteko.Haeba ho hlokahala (sesebelisoa se sebelisoa hangata kapa boemong bo boima ba batho ba tšoanelehang), ho itlhahloba ka nako e bohareng ho etsoa ho etsa bonnete ba hore ts'ebetso ea tekanyo e tšoaneleha 'me phoso ea coefficient e ka har'a sebaka se amohelehang, ho seng joalo data e nepahetseng e ke ke ea fumanoa.
2. Ela hloko ka ho khetheha mocheso oa mokelikeli o lekantsoeng.
Basebelisi ba bangata ba iphapanyetsa sena mme ba nahana hore mocheso o batla o se na thuso.Liteko tsa rona li bontša hore: ha kheloha ea mocheso e le 0.5 ℃, ho kheloha ha viscosity ea lino tse ling ho feta 5%.Ho kheloha ha mocheso ho na le tšusumetso e kholo ho viscosity, mocheso le viscosity.Ka hona, tlhokomelo e khethehileng e lokela ho nkoa ho boloka mocheso oa mokelikeli o lekantsoeng haufi le ntlha ea mocheso o boletsoeng, 'me bakeng sa tekanyo e nepahetseng, ho molemo ho se fete 0.1 ℃.
3. Khetho ea setshelo sa ho lekanya (tube e ka ntle).
Bakeng sa li-viscometers tsa rotary tse peli, bala bukana ea lisebelisoa ka hloko 'me u bapise rotor (cylinder e ka hare) ho latela.Silinda ea kantle, ho seng joalo liphetho tsa tekanyo li tla kheloha haholo.Bakeng sa viscometer e le 'ngoe ea cylinder rotational, radius ea cylinder e ka ntle e lokela ho ba e sa feleng ka molao-motheo.Tekanyo ea sebele e hloka hore bophara bo ka hare ba cylinder e ka ntle e se ka tlase ho boholo bo itseng.Ka mohlala, NDJ-1 rotary viscometer e hloka beaker e lekanyang kapa setshelo se otlolohileng sa tube e seng ka tlase ho 70 mm ka bophara.Liteko li bontšitse hore liphoso tse kholo tsa tekanyo li ka fella haeba bophara bo ka hare ba sekepe bo le nyane haholo, haholo-holo ha rotor no.1 e sebelisoa.
4, ka nepo khetha rotor kapa u fetole lebelo, e le hore boleng ba marang-rang a matla a pakeng tsa 20-90.
Sesebediswa sa mofuta ona se sebedisa dipalo tsa dial plus pointer, mme motswako wa botsitso le ho kgeloha ho bala ho na le 0.5 grids.Haeba ho bala ho le nyane haholo, ho atamela li-grids tse 5, phoso e lekanyelitsoeng e ka ba ho feta 10%.Haeba rotor e nepahetseng e khethiloe kapa lebelo la ho bala ke 50, phoso e amanang le eona e ka fokotsoa ho 1%.Haeba boleng bo bontša ka holimo ho 90, torque e hlahisoang ke selemo e kholo haholo, e atisang ho qhoma le ho senya moriri oa moriri, kahoo re tlameha ho khetha ka nepo rotor le lebelo.
Pampiri ena e hlahisa litaba tse hlokang tlhokomelo ho lekanya viscosity ea hydroxypropyl methyl cellulose, ka tšepo ea hore litaba tse kaholimo li ka u thusa ho etsa liteko.KIMA CHEMICALe khomarela molao-motheo oa "boqapi, moreki pele, boleng pele".Khopolo ea nts'etsopele ea likhoebo ke ho aha holim'a ts'epo le nts'etsopele ea nako e telele, ho lula u nchafatsa lisebelisoa le theknoloji, ho sireletsa tikoloho e tala le nts'etsopele ea theknoloji e phahameng.Khamphani e ikemiselitse ho sebelisana le lihlahisoa tsa boleng bo holimo tsa malapeng le tsa kantle ho naha le metsoalle ka nako e telele, tšebelisano e tiileng.
