Nibihe bintu byahagaritswe bya Carboxymethyl selile?

Igisubizo: CarboxyMethyl selile kandi ifite ibintu bitandukanye bitewe na impamyabumenyi zitandukanye zo gusimburwa. Urwego rwo gusimbuza, ruzwi kandi ku rwego rwo gukora, bisobanura umubare w'impuzandengo ya H mu matsinda atatu yewe hydroxyl yasimbuwe na ch2coona. Iyo amatsinda atatu ya hydroxyl kumurongo ushingiye kuri selile ufite 0.4 mu matsinda ya hydroxyl yasimbuwe na Carboxymethyl, irashobora gushonga mumazi. Muri iki gihe, byitwa 0.4 impamyabumenyi yo gusimbuza cyangwa impamyabumenyi yo gusinya. Impamyabumenyi 0.4-1.2).

Umutungo wa Carboxymethyl selile:

. Ifite itana ryiza no guhambira imbaraga.

. Ifite kandi ubushobozi bwa peteroli no mu gishashara, kandi ni emulsifier ikomeye.

. Ariko, usibye kuri acetate ya acetate, irashobora kongera gushonga mubisubizo bya hydroxide, kandi iy'ibyuma na alumunum byoroshye gukemuka byoroshye kumuti wa amoni.

(4) Iyo igisubizo kihuye na aside kamuri na acide idasanzwe Dukurikije indorerezi, mugihe agaciro ka PH ni 2.5, ubwicanyi n'imvura byatangiye. Kubwibyo Ph 2.5 birashobora gufatwa nkimpamvu ikomeye.

.

(6) Ubushyuhe bugira ingaruka zikomeye kuri viscolity igisubizo cyacyo gitangaje. Ibyatsi bigabanuka bihuye mugihe ubushyuhe buzamutse, naho ubundi. Guhagarara kwa virusire yibibazo bitangaje kubushyuhe bwicyumba ntigihinduka, ariko ubushyuhe burashobora kugabanuka buhoro buhoro mugihe ashyushye buhoro buhoro mugihe ashushanyije hejuru ya 80 ° C igihe kirekire. Mubisanzwe, igihe ubushyuhe butarenze 110 ° C, nubwo ubushyuhe bubikwa kumasaha 3, hanyuma gukonja kugeza 25 ° C, viscosity iracyagaruka muburyo bwambere; Ariko iyo ubushyuhe buhatiwe kugeza 120 ° C kumasaha 2, nubwo ubushyuhe bugaruwe, uruzitiro rutonyanga na 18.9%. .

. Mubisanzwe, mugihe PH yuburyo buke-igisubizo gituruka ku kutabogama, ubushyuhe bwayo nta ngaruka, mugihe cyo gutanga ibitekerezo bisanzwe, niba PH yatandukiriye itabogamiye, viscosity itangira kugabanuka buhoro; Niba PH ya SP yubukirenganuwe bwo hejuru butandukira itabogamye, ubuyobe bwayo buzagabanuka. Kugabanuka gukabije.

. Kurugero, birahuye na kole yinyamanswa, gum Icyarabu, glycerin hamwe na stonarch. Birahuye kandi n'ikirahure cy'amazi, inkuge nyinshi, Urea-formaldehyde resin, Melamine-formaldehyde resin, nibindi, ariko kurwego ruto.

.

(10) Hariho ubushyuhe butatu bwo guhitamo ukurikije ibyifuzo. Kuri Gypsum, koresha sreccosity yo hagati (2% yumubare kuri 300-600mpane ya 300-600Ma · s), niba uhisemo vicosity (1% kuri 2000mpa muri dosiye igomba kumanurwa muburyo bukwiye.

.

. Nyuma yo kwanduza, virusi izagabanuka kandi micow izagaragara. Ongeraho umubare ukwiye ushinzwe kubungabunga mbere birashobora kugumana ubukuru bwayo no gukumira ibyombora igihe kirekire. Biboneka Akabanyamahane ni: Bit (1.2-Imwe), Thiram, Chlorothalolonil, nibindi.

Nigute HydroxyProppopyl Methylcellellse nkumukozi ugumana amazi kuri anhydrite binder?

Igisubizo: HydroxyPropyl Methylcellse nigiciro cyo kugumana amazi menshi kubikoresho bya Gypsum. Hamwe no kwiyongera kw'ibirimo bya hydroxyproppopyl methylcellse. Kugumana amazi ya Gypsum yashimangiye ibintu byiyongera vuba. Iyo nta mazi agumana umukozi, umubare wo kugumana amazi wa Gypsum yashimangiye ibikoresho bigera kuri 68%. Iyo umubare w'amazi ugagumana umukozi ni 0.15%, igipimo cyo kugumana amazi ya Gypsum cyashimangiye ibikoresho bishobora kugera kuri 90.5%. Na koherezwa kwamazi bisabwa plaster yo hepfo. Igipimo cyumukozi ugumana amazi urenze 0.2%, byongera uruganda, kandi umubare wamazi wogumana amazi yiyongera cyane. Imyiteguro y'ibikoresho bya Anhydrite. Igipimo gikwiye cya hydroxypropyl methylcellse ni 0.1% -0.15%.

Ni izihe ngaruka zitandukanye za selile zitandukanye kuri plaster ya Paris?

Igisubizo: Byombi CarboxyMethyl Thansi na Methyl selile irashobora gukoreshwa nkurwego rugumana amazi ya Plaster wa Plaster, ariko ni yo fatizo rya Corbol Methyl selile ni afmixture nziza yibikoresho bya Gypsum Kwinjizamo kugumana amazi, kubyimba, gukomera, no gusunika, usibye ko ubwoko bumwe bubi bafite ingaruka zidindiza. hejuru kuruta carboxymethyl selile. Kubera iyo mpamvu, ibikoresho byinshi bya gepsum byujuje uburyo bwo kwiyongera kwa Carboxymethyl selilexymethyl selilexymethyl selilexymethyl selilexymethyl selile ya kanseri, kandi igira ingaruka nziza za Metboyl. Muri ubu buryo, gukora imirimo yo kugumana amazi ya Gypsum Ibikoresho bya Gypsum nibikorwa byuzuye bya Gypsum Ibikoresho bya Gypsum birashobora kunozwa, mugihe ubwiyongere buke bubikwa kumwanya muto.
