1. Zita rekuti hydroxypropyl methylcellulose rinobva kupi?
——Mhinduro: Hydroxypropyl Methyl Cellulose, Chirungu: Hydroxypropyl Methyl Cellulose Kupfupikiswa: HPMC kana MHPC Zita rekuti: Hypromellose; Cellulose Hydroxypropyl Methyl Ether; Hypromellose, Cellulose, 2-hydroxypropylmethyl Cellulose ether. Cellulose hydroxypropyl methyl ether Hyprolose.
2. Chii chinonyanya kushandiswa nehydroxypropyl methylcellulose (HPMC)?
——Mhinduro: HPMC inoshandiswa zvakanyanya muzvinhu zvekuvaka, machira ekuputira, maresini ekugadzira, zviumbwa zvedoro, mishonga, chikafu, machira, kurima, zvizoro, fodya nedzimwe nzvimbo dzeindasitiri. HPMC inogona kukamurwa kuita giredhi rekuvaka, giredhi rechikafu uye giredhi remishonga zvichienderana nechinangwa. Parizvino, zvigadzirwa zvakawanda zvemumba ndezve giredhi rekuvaka. Mugiredhi rekuvaka, putty powder inoshandiswa zvakanyanya, inenge 90% inoshandiswa putty powder, uye yasara inoshandiswa simende mortar neglue.
3. Kune mhando dzakasiyana dzehydroxypropyl methylcellulose (HPMC), uye ndedzipi musiyano uripo pakushandiswa kwadzo?
——Mhinduro: HPMC inogona kukamurwa kuita mhando yekukurumidza uye mhando yekupisa. Zvigadzirwa zvemhando yekukurumidza zvinopararira nekukurumidza mumvura inotonhora uye zvinonyangarika mumvura. Panguva ino, mvura haina viscosity nekuti HPMC inongopararira mumvura isina kunyungudika chaiko. Maminetsi angangoita maviri, viscosity yemvura inowedzera zvishoma nezvishoma, ichigadzira colloid yakajeka ine viscous. Zvigadzirwa zvinonyungudika, kana zvikasangana nemvura inotonhora, zvinogona kupararira nekukurumidza mumvura inopisa uye zvinonyangarika mumvura inopisa. Kana tembiricha yadzikira kusvika kune imwe tembiricha, viscosity inoonekwa zvishoma nezvishoma kusvika yagadzira colloid yakajeka ine viscous. Mhando yekupisa inonyungudika inogona kushandiswa chete muputty powder nemortar. Mu liquid glue nependi, pachava neboka rezviitiko uye hazvigone kushandiswa. Instant type ine mashandisirwo akasiyana-siyana. Inogona kushandiswa muputty powder nemortar, pamwe neliquid glue nependi, pasina chero zvinopesana.
4. Ungasarudza sei hydroxypropyl methylcellulose (HPMC) yakakodzera kune zvinangwa zvakasiyana?
—— Mhinduro::Kushandisa putty powder: Zvinodiwa zvakaderera, uye viscosity i100,000, zvinokwana. Chinhu chakakosha kuchengetedza mvura zvakanaka. Kushandisa mortar: zvinodiwa zvakanyanya, viscosity yakawanda, 150,000 zviri nani. Kushandisa glue: zvigadzirwa zvepakarepo zvine viscosity yakawanda zvinodiwa.
5. Chii chinofanira kutariswa pakushandiswa chaiko kwehukama huripo pakati pekusimba uye tembiricha yeHPMC?
——Mhinduro: Kupenya kweHPMC kunoenderana nekupisa, kureva kuti, kupenya kunowedzera sezvo kupisa kuchiderera. Kupenya kwechigadzirwa chatinowanzo taura nezvacho kunoreva mhedzisiro yekuyedzwa kwe2% yemvura inobuda pakupisa kwe20 degrees Celsius.
Mukushandiswa kwaro, zvinofanira kucherechedzwa kuti munzvimbo dzine musiyano mukuru wekupisa pakati pezhizha nechando, zvinokurudzirwa kushandisa viscosity yakaderera munguva yechando, izvo zvinonyanya kubatsira pakuvaka. Zvikasadaro, kana tembiricha yakaderera, viscosity ye cellulose ichawedzera, uye ruoko ruchanzwa rwakasimba pakukwesha.
Viscosity yepakati: 75000-100000 inonyanya kushandiswa pakuisa putty
Chikonzero: kuchengetedza mvura zvakanaka
Kusviba kwakanyanya: 150000-200000 Inonyanya kushandiswa pa polystyrene particle thermal insulation mortar rabha upfu uye vitrified microbead thermal insulation mortar.
Chikonzero: Kusviba kwacho kwakanyanya, dhaka harisi nyore kudonha, kudonha, uye kuvakwa kwacho kwavandudzika.
6. HPMC i-non-ionic cellulose ether, saka chii chinonzi non-ionic?
——Mhinduro: Mumashoko emunhuwo zvake, ma non-ion zvinhu zvisingaite ioni mumvura. Ionization zvinoreva maitiro apo electrolyte inosanganiswa kuita ma ioni ane chaji anogona kufamba zvakasununguka mune chimwe chinhu chinonyungudutsa (senge mvura, doro). Semuenzaniso, sodium chloride (NaCl), munyu watinodya zuva nezuva, unonyunguduka mumvura uye unoite ioni kuti igadzire ma sodium ions anofambiswa zviri nyore (Na+) ane chaji yakanaka uye ma chloride ions (Cl) ane chaji yakaipa. Kureva kuti, kana HPMC ikaiswa mumvura, haizoparadzi kuita ma ioni ane chaji, asi inovapo muchimiro chemamorekuru.
