Embonini yokucubungula amakhemikhali, ukukhetha izinto zokwakha kungaphezu nje kokusebenza kahle—kuyindaba yokuphepha, ukuqina, kanye nokonga izindleko. Imishini esetshenziswa kulo mkhakha kumele imelaneamakhemikhali anolaka, amazinga okushisa aphezulu, ukucindezeleka okuphezulu, futhiizindawo ezigqwalisayonsuku zonke. Yilaphoinsimbi engagqwalikubonakala kuyisinqumo esiyingqayizivele.
Kodwa akuzona zonke izinsimbi ezingagqwali ezidalwe zilingana. Ukukhetha izinga elifanele kubalulekile ekufezeni impilo ende yesevisi, ukugwema ukwehluleka kwemishini, nokuqinisekisa ukusebenza kahle. Kulesi sihloko, sihlola izici ezibalulekile zokukhetha insimbi engagqwali ekucubungulweni kwamakhemikhali, amazinga avame kakhulu, kanye nezinzuzo zazo ezithile. Zilethwe kuwe yii-sasalloy, umlingani wakho othembekile ezintweni zensimbi engagqwali ukuze kube ngcono ezimbonini.
Kungani Insimbi Engagqwali Ibalulekile Ekucutshungulweni Kwamakhemikhali
Insimbi engagqwali inikeza inhlanganisela eyingqayizivele yeukumelana nokugqwala, amandla, ukumelana nokushisa, kanye nokuhlanzekaUkwakheka kwayo okucebile nge-chromium kwakha ungqimba lwe-oxide olungasebenzi oluvikela ubuso ekuhlaselweni ngamakhemikhali—ngisho noma kukhona ama-asidi aqinile, ama-alkali, kanye nezinyibilikisi.
Izinzuzo ezibalulekile zezindawo zamakhemikhali zifaka:
-
Ukumelana okuhle kakhulu nokugqwala kwemigodi kanye ne-crevice
-
Izakhiwo eziqinile zemishini kokubili emazingeni okushisa aphezulu naphansi
-
Kulula ukwenziwa nokushisela
-
Ukugcinwa okuphansi kanye nokuphila isikhathi eside kwenkonzo
-
Ukuhambisana nezinhlelo ze-CIP ezihlanzekile nezihlanzekile
At i-sasalloy, sihlinzeka ngemikhiqizo yensimbi engagqwali esezingeni lamakhemikhali ehlangabezana nezindinganiso zomhlaba wonke kanye nezidingo ezithile zamakhasimende.
Izinto Okufanele Uzicabangele Lapho Ukhetha Insimbi Engagqwali
Lapho bekhetha insimbi engagqwali yokusetshenziswa kwamakhemikhali, onjiniyela kufanele bahlole:
-
Ukwakheka kwamakhemikhali kwemidiya yenqubo
-
Ukugxila, izinga lokushisa, kanye nengcindezi
-
Uhlobo lokugqwala (isb., okuvamile, ukuqhekeka kwemigodi, ukuqhekeka kokucindezeleka)
-
