Ukwahlukaniswa Nokuhlaziywa Kwezicelo Zamathangi Esitoreji Anemigqa

Emkhakheni wamakhemikhali, ukudla, imithi, njll., amathangi okugcina ayimpahla ebalulekile yokugcina uketshezi noma amagesi. Phakathi kwazo, amathangi okugcina anemigqa abe yisixazululo esithandwayo sezimboni eziningi ngenxa yokumelana nokugqwala okuhle kakhulu nokuphepha. Lesi sihloko sizokwethula ukuhlukaniswa kwezigaba zamathangi esitoreji anemigqa kanye nezimo zohlelo lwawo ngokuningiliziwe ukuze sisize abasebenzisi bakhethe kangcono uhlobo lwethangi lokugcina elifanelana nezidingo zabo.

Ukuhlukaniswa ngempahla ye-lining

Ingqikithi yamathangi okugcina anemigqa isezintweni zawo zolwelwesi. Izinto ezihlukile zinquma ukumelana nokugqwala, ukumelana nezinga lokushisa kanye nobubanzi obuphakathi obusebenzayo bethangi lokugcina. Izigaba ezijwayelekile zihlanganisa:

1. Amathangi e-polyethylene (PE) anemigqa yokugcina

Amathangi okugcina ane-polyethylene anemigqa asetshenziswa kakhulu embonini yamakhemikhali ngenxa yokuphikiswa kwawo okuhle kakhulu kwe-asidi ne-alkali kanye nezindleko eziphansi. Izinto ze-PE zinokuzinza kwamakhemikhali okuqinile futhi zifanele ukugcina ama-asidi abuthakathaka, ama-alkali abuthakathaka nezinye izinyibilikisi eziphilayo. Ububi bayo ukuthi ukumelana kwayo nezinga lokushisa kulinganiselwe futhi ngokuvamile kulungele izindawo ezisukela ku -20 kuya ku-60 degree.

2. Amathangi e-Polypropylene (PP) anemigqa yokugcina

Amathangi e-polypropylene okugcina umugqa anokumelana nokushisa okuphezulu kune-PE futhi angakwazi ukumelana nebanga lokushisa -20℃kuya ku-100 degree, elifanele ukugcinwa kwabezindaba zamakhemikhali emazingeni okushisa aphezulu. Impahla ye-PP futhi inokumelana nokugqwala okuhle kakhulu futhi imvamisa isetshenziselwa ukugcina uketshezi olubolayo njengama-asidi aqinile nama-alkali.

3. Amathangi e-Fluoroplastic (PTFE/FEP) anemigqa yokugcina

Amathangi esitoreji anemigqa ye-Fluoroplastic angenye yezinhlobo zamathangi okugcina angagqwali kakhulu futhi afanele ukugcina izinto ezigqwala kakhulu njenge-hydrofluoric acid ne-concentrated sulfuric acid. Izinto ze-PTFE (polytetrafluoroethylene) kanye ne-FEP (i-fluorinated ethylene propylene) zinamandla angaphezulu aphansi kakhulu kanye nokungangenisi kwamakhemikhali futhi awahlangani nanoma imaphi amakhemikhali, kodwa ayabiza futhi avame ukusetshenziswa emikhakheni ekhethekile yezimboni.

Ukuhlukaniswa ngesakhiwo

Isakhiwo sethangi lokugcina elinomugqa nalo lithinta izimo zalo ezisebenzayo, ezihlukaniswe kakhulu zibe:

1. Ithangi lokugcina eligcwele umugqa

Udonga lwangaphakathi lwethangi lokugcina elinomugqa ogcwele lumbozwe ngokuphelele ngezinto ezisetshenziswayo, ezifanele ukugcina imidiya egqwala kakhulu kanye nokuqinisekisa ukumelana nokugqwala okuphelele kwethangi.

2. Ithangi lokugcina elinemigqa kancane

Amathangi okugcina anemigqa eyingxenye asebenzisa izinto zokwenziwa kolayini kuphela engxenyeni ethinta indawo ebolayo, elungele ukugcina imidiya engagqwali futhi inganciphisa izindleko.

Izinkambu zohlelo lokusebenza

Amathangi okugcina anemigqa asetshenziswa kakhulu kumakhemikhali, ukudla, imithi, ukuvikelwa kwemvelo kanye nezinye izimboni. Embonini yamakhemikhali, asetshenziselwa ukugcina ama-acids, ama-alkali, ama-organic solvents, njll.; embonini yokudla, asetshenziselwa ukugcina imikhiqizo yobisi, amajusi, njll.; emkhakheni wezemithi, asetshenziselwa ukugcina{3}imithi yoketshezi ehlanzekile.

Ukukhetha ithangi elifanele lokugcina umugqa kudinga ukucatshangelwa okuphelele kwezici ezimaphakathi, izidingo zokushisa kanye nesabelomali sezindleko. Ukuqonda izigaba ezahlukene kungasiza izinkampani ukuthi zithuthukise ukukhetha kwamathangi futhi zithuthukise ukusebenza kahle kokukhiqiza nokuphepha.
