Uburyo bwo gupima uburyo bwo kubika amazi ya selile ether

Cellulose ether ninyongera ikoreshwa cyane mumashanyarazi yumye. Ether ya selile ifite uruhare runini mumashanyarazi yumye. Nyuma ya selile ya selile muri minisiteri imaze gushonga mumazi, ingaruka nziza yibintu bya sima muri sisitemu iremezwa kubera ibikorwa byubuso. Nka colloid ikingira, selulose ether "ipfunyika" ibice bikomeye kandi ikora firime yo gusiga amavuta hejuru yinyuma yayo, bigatuma sisitemu ya minisiteri ihagarara neza kandi igateza imbere umuvuduko no gutuza kwa minisiteri mugihe cyo kuvanga. Ubwubatsi bwubaka. Bitewe nuburyo bwimiterere ya molekuline, umuti wa selulose ether utuma amazi yo muri minisiteri atoroha kubura, kandi akayarekura buhoro buhoro mugihe kirekire, bigatuma minisiteri igumana amazi meza kandi ikora. Kugumana amazi ya selulose ether nicyo kintu cyingenzi kandi cyibanze. Kugumana amazi bivuga ubwinshi bwamazi yagumishijwe na minisiteri nshya ivanze ku musozo nyuma yo gukora capillary. Ikizamini cyo gufata amazi ya selulose ether kuri ubu ntigifite uburyo bwo gupima mugihugu, kandi mubisanzwe ababikora ntibatanga ibipimo bya tekiniki, bizana ikibazo kubakoresha mukoresha no kubisuzuma. Twifashishije uburyo bwo gupima ibindi bicuruzwa, ethers ya selile ikurikira irakusanyirijwe hamwe Uburyo bwo gupima amazi ni kubiganiraho.

1. Uburyo bwo kuvoma Vacuum

Ubushuhe mu gihirahiro nyuma yo kuyungurura

Uburyo bwerekeza ku nganda za JC / T517-2005 “Plastering Gypsum” inganda, kandi uburyo bwo gukora ibizamini bwerekeza ku mwimerere w’Ubuyapani (JISA6904-1976). Mugihe cyikizamini, uzuza umuyoboro wa Buchner na minisiteri ivanze n’amazi, ubishyire ku icupa ryungurura, utangire pompe ya vacuum, hanyuma uyungurure muminota 20 munsi yumuvuduko mubi wa (400 ± 5) mm Hg. Noneho, ukurikije ubwinshi bwamazi mumazi mbere na nyuma yo kuyungurura, bara igipimo cyo kubika amazi kuburyo bukurikira.

Kugumana amazi (%) = ubuhehere mu gihuru nyuma yo kuyungurura / ubushuhe mu gihuru mbere yo kuyungurura) KX)

Uburyo bwa vacuum burasobanutse neza mugupima igipimo cyo gufata amazi, kandi ikosa ni rito, ariko risaba ibikoresho nibikoresho bidasanzwe, kandi ishoramari ni rinini.

2. Shungura uburyo bw'impapuro

Uburyo bwo kuyungurura impapuro nugucira urubanza amazi ya selile ya selile ukoresheje amazi yo kuyungurura. Igizwe nicyuma gipima impeta ifite uburebure runaka, impapuro zungurura hamwe nisahani ishigikira. Hano hari ibice 6 byiyungurura impapuro munsi yikigereranyo, igipapuro cya mbere ni impapuro zungurura byihuse, naho ibice 5 bisigaye ni buhoro buhoro. Koresha impagarike isobanutse kugirango upime uburemere bwa pallet hamwe nibice 5 byimpapuro ziyungurura buhoro, banza usukemo minisiteri mubizamini nyuma yo kuvanga no kubisiba neza, hanyuma ubireke bihagarare muminota 15; hanyuma upime uburemere bwa pallet nibice 5 byuburemere bwimpapuro. Kubarwa ukurikije formula ikurikira:

M = / S.

M - gutakaza amazi, g / nm?

uburemere bwa nu_pallet + ibice 5 byimpapuro zungurura buhoro; g

m2_ Uburemere bwa pallet + ibice 5 byimpapuro zungurura buhoro nyuma yiminota 15; g

Ibiryo bya S_area kubigeragezo?

Urashobora kandi kwitegereza mu buryo butaziguye urugero rw'amazi yinjira mu mpapuro zungurura, uko amazi yinjira mu mpapuro zungurura, niko gufata neza amazi. Uburyo bwikizamini buroroshye gukora, kandi ibigo rusange birashobora kuzuza ibisabwa.

3. Uburyo bwo kwipimisha hejuru yumwanya:

Ubu buryo bushobora kwerekeza kuri GB1728 “Kugena Igihe cyo Kuma cya Firime Irangi na Filime ya Putty”, gusiba minisiteri ivanze ku kibaho cya sima ya asibesitosi, hanyuma ukagenzura umubyimba kuri 3mm

Uburyo bwa 1: uburyo bwo gukina umupira

Shyira witonze umupira wipamba winjiza hejuru ya minisiteri, kandi mugihe gisanzwe, koresha umunwa wawe kugirango umupira wipamba utareshya na santimetero 10-15 uvuye kumupira w ipamba, hanyuma uhite witonze umupira wipamba werekeza kuri horizontal. Niba ishobora gutwarwa kandi ntamutwe w ipamba usigaye hejuru ya minisiteri, hejuru ifatwa nkuwumye, umwanya muremure, niko gufata amazi neza.

Uburyo bwa kabiri, uburyo bwo gukoraho urutoki

Kora witonze hejuru ya minisiteri ukoresheje intoki zisukuye mugihe gisanzwe. Niba yumva ifatanye gato, ariko nta minisiteri ihari ku rutoki, birashobora gufatwa nkaho ubuso bwumye. Umwanya muremure, niko gufata amazi neza.

Uburyo bwavuzwe haruguru, uburyo bwo kuyungurura impapuro nuburyo bwo gukoraho urutoki bikoreshwa cyane kandi byoroshye; abakoresha barashobora kumenya mbere na mbere ingaruka zo gufata amazi ya selile ether binyuze muburyo bwavuzwe haruguru.
