imwe. Itandukaniro riri hagati ya hydroxypropyl methylcellse (HPMC) na hydroxypropyl methylcellse (HPMC)
1. Kugaragara: hydroxypropyl methylcellse hpmc isa cyane kandi ifite ubucucike buke, kuva kuri 0.3-0.4g / ml; HydroxyPropyl Methylcellselse Hpmc ifite amazi meza kandi yumva aremereye, kandi hari itandukaniro rikomeye mubicuruzwa byukuri.
2. Imiterere: HydroxyPropyl Methylcellse Ifu ya HPMC ni fibrous munsi ya microscope cyangwa ikirahure kinini; Mugihe hydroxyproppopyl methylcellse hpmc irashobora kubahirizwa nkibisubizo bya granular cyangwa kristu munsi ya microscope cyangwa ikirahure.
3. Odor: HydroxyPropyl Methylcellse HPMC ntishobora kunuka n'umunuko wa Amoni, udusimba n'inzoga; HydroxyPropyl Methylcellse HPMC irashobora kunuka impumuro zose, nubwo idaryoshye, izumva iremereye.
4. Igisubizo kiratangaje: hydroxypropyl methylcellses igisubizo kirasobanutse kirasobanutse, umukono usobanutse neza, umukono muremure, igipimo cyo kugumana amazi ≥ 97%; Amashanyarazi ya hydroxypropyl methylcellse hpmc igisubizo cyamazebwe ni turbid, kandi igipimo cyo kugumana amazi biragoye kugera kuri 80%.
Icya kabiri, kugumana amazi ya hydroxypropyl methylcellsel methmc, gutandukanya ibyiza nibibi:
Kugumana amazi ya methyl selile ether imiterere yubushyuhe nicyo kimenyetso cyingenzi kugirango utandukane ubwiza bwa methyl. Ibintu nkubushyuhe bwikirere, ubushyuhe hamwe numuvuduko wumuvuduko wumuyaga bizagira ingaruka kumibare y'amaraso muri sima na parpsum. Kubwibyo, mubihe bitandukanye, hariho itandukaniro muburyo bwo kugumana amazi hamwe na HPMC imwe yongeyeho. Mubwubatsi bwihariye, ingaruka zo kugumana amazi zirashobora guhindurwa no kwiyongera cyangwa kugabanya umubare wa HPMC yongeyeho. Ibicuruzwa byiza bya hydroxypropyl methylcellses hpmc irashobora gukemura ikibazo cyo kugumana amazi munsi yubushyuhe bwinshi.
Ububiko buke bukabije burashobora gutatana neza kandi neza kandi bivuye ku bicuruzwa bishingiye kuri sitali no ku ruhushya, kandi bitera imikino ihamye buhoro buhoro biremeza buhoro buhoro imbaraga z'ingwate n'imbaraga zo kwikuramo ibikoresho. HydroxyPropyl Methylcellse HPMC, ubumwe bwabwo ni bwiza cyane kuri hydroxyl na etherroxy thisgen hamwe na hydroxyle ihinduka amazi yubusa, bityo bigatuma ogisizeni ihinduka amazi yubusa, bityo yongeraho amavuta yo kwiteranya amazi yo kwiteranya amazi n'ubushyuhe bwo hejuru no kugera ku ngufu hejuru.
Therefore, in high-temperature summer construction, in order to achieve the water retention effect, it is necessary to add high-quality HPMC products in sufficient quantities according to the formula, otherwise, there will be insufficient hydration, reduced strength, cracking, hollowing and shedding caused by excessive drying. ibibazo, ariko kandi byongera ingorane zububiko. Mugihe ubushyuhe butonyanga, umubare wamazi HPMC yongeyeho irashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo kugumana amazi zirashobora kugerwaho.
3. Iseswa rya hydroxypropyl methylcellse hpmc
Mu nganda zubwubatsi, hydroxyPropyl methylcellse hpmc ikunze gushyirwa mumazi atabogamye, kandi ibicuruzwa bya HPMC byashojwe wenyine kugirango ucire igiciro cyivumburwa. Nyuma yo gushyirwa mumazi adafite aho abogamiye wenyine, ibicuruzwa bihindagurika byihuse nta gutatana nigicuruzwa kidafite ubuvuzi bwo hejuru; Nyuma yo gushyirwa mumazi adafite aho abogamiye wenyine, ibicuruzwa bishobora gutatana kandi ntibitongana ni ibicuruzwa bifite ubuvuzi bukabije. Iyo ubuso butazwi hydroxypropyl methylcellse hpmc yashonze wenyine, ibice byayo imwe bishonga vuba kandi bitera amazi vuba, bigatuma amazi atagisimburanaga, ubu yitwa gusenywa buhoro mubicuruzwa byisoko.
Ubuso-buvuwe hydroxypropyl methylcellse ibicuruzwa bya HPMC, mumazi adafite aho abogamiye, ibice byihariye birashobora gutatatana nta agglomera, ariko virusi yibicuruzwa ntabwo izahita itahita. Nyuma yigihe runaka, imiterere yimiti yubuvuzi hejuru irasenyutse, kandi amazi arashobora gushonga ibice bya HPMC. Muri iki gihe, ibicuruzwa byatatanye byuzuye kandi byinjijwe n'amazi ahagije, bityo ibicuruzwa ntibizatera imbaraga cyangwa bitera inyuma nyuma yo guseswa. Gutandukanya umuvuduko no gusebanya byihuta biterwa nurwego rwo kuvura hejuru. Niba ubuvuzi bwo hejuru buke, umuvuduko utatatanya urangiye kandi umuvuduko ukomera urihuta; Mugihe ibicuruzwa bifite ubuvuzi bwimbitse bufite umuvuduko wihuse kandi wihuta. Niba ushaka gukora uruhererekane rwibicuruzwa bishonga vuba muri iyi leta, urashobora guta ibintu bike bya alkaline mugihe zashonje wenyine. Isoko ryaho risanzwe rivugwa nkibicuruzwa ako kanya. Ibiranga ibicuruzwa bya HPMC bivuwe cyane ni: Mu gisubizo cy'amazi, ibice birashobora gutatana, birashobora gushonga vuba muri leta ya alkaline, kandi ishonga buhoro buhoro muri leta itabogamye na acide.
Ibiranga hydroxyproppoppopyl methylcellsel methylcellse hpmc ni: agace gato ka alkaline, ariko kadashobora gutatana mubice byamazi, bikavamo guhubuka no guterana. Mu gikorwa nyacyo, nyuma yo gutatanya kw'umubiri muri uruhererekane rw'ibicuruzwa n'ibice bikomeye nk'ifu ya rubber nk'ifu ya rubber, sima, umucanga, n'ibindi, igipimo cy'imivugo kirihuta cyangwa ngo agglomera. Iyo bibaye ngombwa gushonga ibicuruzwa bya HPMC ukundi, uruhererekane rwibicuruzwa rugomba gukoreshwa witonze, nkuko bizagenda bitera imbere kandi ufata hamwe. Niba ari ngombwa gusesa hydroxypropyl-hydroxyproppopyl methylcellse ongera ukwayo
Mubikorwa nyabyo, uruhererekane rwibicuruzwa akenshi bishonga nyuma yo gutatana nibindi bikoresho bikomeye muburyo bwa alkaline, kandi igipimo cyarwo nticyari gitandukanye nibicuruzwa bitavuwe. Birakwiriye kandi gukoreshwa mubicuruzwa byashonze wenyine, nta caking cyangwa ibibyimba. Icyitegererezo cyihariye cyibicuruzwa birashobora gutorwa ukurikije igipimo cyivumburwa gisabwa nubwubatsi.
Mugihe cyubwubatsi, yaba sima ya sima cyangwa gypsum ishingiye kuri gypsum, benshi muribo ni sisitemu ya alkaline, kandi ingano ya HPMC yongeyeho ni ntoya, ishobora gutatanya muriyi duce. Iyo amazi yongeyeho, HPMC izashonga vuba.
