Kodi kuyeza mamasukidwe akayendedwe a HPMC?

Njira zodzitetezera poyezera kukhuthala kwa hydroxypropyl methyl celluloseMtengo wa HPMC? Tikamayesa kukhuthala kwa cellulose. Pofuna kutsimikizira kulondola kwa zotsatira za mayeso, chidwi chapadera chiyenera kuperekedwa ku mbali zinayi zotsatirazi.

1. Zizindikiro zogwirira ntchito za chipangizocho ziyenera kukwaniritsa zofunikira za malamulo ovomerezeka a dziko lonse.

Thehydroxypropyl methyl celluloseChida choyezera kukhuthala chimagwiritsidwa ntchito poyeserera. Ngati kuli kofunikira (chidacho chimagwiritsidwa ntchito mobwerezabwereza kapena mumkhalidwe wovuta wa oyenerera), kudziyesa kwapakatikati kumachitidwa kuti zitsimikizire kuti ntchito yoyezera imakhala yoyenera ndipo cholakwika cha coefficient chiri mkati mwazovomerezeka, mwinamwake deta yolondola sichingapezeke.

2. Samalani kwambiri kutentha kwa madzi omwe akuyezedwa.

Ogwiritsa ntchito ambiri amanyalanyaza izi ndikuganiza kuti kutentha kumakhala kopanda ntchito. Zoyesera zathu zikuwonetsa kuti: kutentha kwapang'onopang'ono ndi 0.5 ℃, kupatuka kwa mamasukidwe amadzimadzi kumaposa 5%. Kupatuka kwa kutentha kumakhudza kwambiri mamasukidwe akayendedwe, kutentha ndi mamasukidwe akayendedwe. Choncho, chisamaliro chapadera chiyenera kuchitidwa kuti kutentha kwa madzi omwe amayezedwa kukhale pafupi ndi kutentha komweku, ndipo kuti muyese molondola, ndi bwino kuti musapitirire 0.1 ℃.

3. Kusankha chidebe choyezera (chubu chakunja).

Kwa ma viscometers ozungulira a migolo iwiri, werengani buku la chida mosamala ndikugwirizanitsa rotor (silinda yamkati) moyenerera. Silinda yakunja, apo ayi zotsatira zoyezera zidzasokonekera kwambiri. Kwa silinda imodzi yozungulira viscometer, radius ya silinda yakunja iyenera kukhala yopanda malire. Muyezo weniweni umafuna kuti m'mimba mwake wamkati wa silinda yakunja sikuchepera kukula kwake. Mwachitsanzo, NDJ-1 rotary viscometer imafuna beaker yoyezera kapena chidebe chowongoka cha chubu chosachepera 70 mm m'mimba mwake. Kuyesera kwawonetsa kuti zolakwika zazikulu zoyezera zimatha kuchitika ngati mkatikati mwa chotengeracho ndi chochepa kwambiri, makamaka ngati rotor no. 1 imagwiritsidwa ntchito.

4, sankhani molondola rotor kapena sinthani liwiro, kuti mtengo wa gridi yamagetsi ukhale pakati pa 20-90.

Chida chamtunduwu chimagwiritsa ntchito mawerengedwe a dial plus pointer, ndipo kuphatikiza kukhazikika ndi kupotoza kuwerenga kumakhala ndi ma gridi 0.5. Ngati kuwerengako kuli kochepa kwambiri, kuyandikira ma gridi 5, cholakwikacho chikhoza kukhala choposa 10%. Ngati rotor yolondola yasankhidwa kapena kuwerengera liwiro ndi 50, cholakwikacho chikhoza kuchepetsedwa mpaka 1%. Ngati mtengo ukuwonetsa pamwamba pa 90, makokedwe opangidwa ndi kasupe ndi aakulu kwambiri, omwe amatha kukwawa ndikuwononga tsitsi, choncho tiyenera kusankha molondola rotor ndi liwiro.

Pepalali likuwonetsa zinthu zomwe zikufunika kusamaliridwa pakuyezera kukhuthala kwa hydroxypropyl methyl cellulose, ndikuyembekeza kuti zomwe zili pamwambapa zingakuthandizeni kuyesa.KIMA CHEMICALamatsatira mfundo ya "zatsopano, kasitomala poyamba, khalidwe loyamba". Lingaliro lachitukuko chabizinesi ndikumanga pakukhulupirirana kwanthawi yayitali ndi chitukuko, kukonza zida ndi ukadaulo nthawi zonse, kuteteza chilengedwe chobiriwira komanso chitukuko chaukadaulo. Kampaniyo ndi wokonzeka kugwirizana ndi zoweta ndi achilendo mankhwala apamwamba ndi mabwenzi kwa nthawi yaitali, mgwirizano moona mtima.
