Umhlahlandlela Wokuthenga Amabhuzu E-Biochemical: Indlela Yokukhetha Izitshalo Zamakhemikhali, Amalebhu, Ukulawulwa Kobhubhane, kanye Nokwelashwa Kwamanzi Angcolile

Umhlahlandlela Wokuthenga Amabhuzu E-Biochemical: Indlela Yokukhetha Izitshalo Zamakhemikhali, Amalebhu, Ukulawulwa Kobhubhane, kanye Nokwelashwa Kwamanzi Angcolile

Ezitshalweni zamakhemikhali, emalabhorethri ezinto eziphilayo, ezindaweni zokulawula ubhubhane, nasezitshalweni zokwelashwa kwamanzi angcolile, abasebenzi ababhekene nodaka namanzi ajwayelekile. Babhekene nama-asidi aqinile, ama-alkali aqinile, amagciwane, amabhaktheriya, kanye nezinyibilikisi ezinobuthi. Amabhuzu emvula ajwayelekile noma amabhuzu okuphepha asefektri angadliwa ngamakhemikhali noma awakwazi ukuvimba amagciwane ukuthi angangeni. Ngakho amabhuzu e-biochemical awawona nje amagiya okuphepha ajwayelekile. Ayisithiyo sokugcina ngokumelene nezingozi zamakhemikhali nezezinto eziphilayo. Lo mhlahlandlela ukutshela ukuthi ungakhetha kanjani ngokusekelwe emsebenzini wakho, yiziphi izici ezibalulekile okufanele uzibheke, ukuthi ubude bebhuzu udingani, ukuthi yimaphi amaphepha okuphepha okufanele uwahlole, ukuthi ungakhetha kanjani osayizi, ukuthi ungathenga kanjani ngobuningi, kanye nomehluko phakathi kwamabhuzu alahlwayo nalasetshenziswa kabusha.

Ukukhetha Ngokwesimo: Izindawo Ezine Ezijwayelekile, Izidingo Ezihlukene

Ama-workshop nama-lab amakhemikhali avame ukuba nama-asidi aqinile njenge-sulfuric acid, i-hydrofluoric acid, kanye nezinyibilikisi eziphilayo. Uma ukhetha amabhuzu alezi zindawo, gxila ekumelaneni ne-acid/alkali kanye nokumelana nokugeleza kwamanzi. Irabha kumele ilinganiswe ngamakhemikhali athile nokuthi aqine kangakanani, hhayi nje ilebula "elingamelani namakhemikhali" elingacacile. Ezindaweni zokulawula ubhubhane kanye nokubulala amagciwane, izingozi ezinkulu ngamagciwane, amabhaktheriya, kanye nezibulali-magciwane. Ngakho amabhuzu kumele abe nesitifiketi sokuvikelwa kwezinto eziphilayo, njenge-ASTM F1671 ukuze angene egciwaneni. Kumele futhi amelane nezibulali-magciwane ezisekelwe ku-chlorine, i-peracetic acid, kanye nezinye izihlanzi ezinamandla. Ezitshalweni zokwelapha amanzi amdaka, izingozi zixubene: amagesi aqothulayo (njenge-hydrogen sulfide), amagciwane odakeni, kanye nezingcezu ezibukhali zemfucumfucu. Ngakho amabhuzu adinga ukumelana namakhemikhali, ukumelana nokubhoboza, ukumelana nokushelela, kanye nokumelana nokugeleza kwamanzi. Ibhuzu elide, elingenamthungo, nelinobuthi lingcono kakhulu.

Amapharamitha Ayinhloko Okufanele Uwahlole: Ukumelana ne-Acid/Alkali, Ukumelana Nokugcwala, Ukuvikelwa Komthelela, Ukuvikelwa Kokubhoboza

Zonke lezi zinto ezine zibaluleke kakhulu. Ukuze uthole ukumelana ne-asidi/i-alkali, funa idatha ethile yokuhlola. Lokho kusho ukuthi ibhuthi lingahlala isikhathi esingakanani kumakhemikhali anamandla angaphezu kuka-30% ngaphandle kokuvuvukala, ukuthamba, noma ukuqhekeka. Ukumelana nokugeleza kwamanzi kusho ukuthi kokubili uketshezi namagesi akukwazi ukudlula, kufaka phakathi umusi oyingozi ongama-molecule amancane. Ukuhlolwa okuqinile kusebenzisa amagesi okulandelela noma izimpawu zemisebe. Ukuvikelwa komthelela nokubhoboza akukho kuzo zonke izibhuthi ze-biochemical, kodwa kuyadingeka ezindaweni zasefektri, njengalapho wenza ukulungiswa esitshalweni samakhemikhali noma uphatha imfucuza eyingozi. Isivalo senzwane sensimbi noma esihlanganisiwe kanye ne-Kevlar puncture esiphakathi sivikela ezintweni eziwayo nezinzipho ezibukhali.

Ukukhetha Ukuphakama Komgodi: Amabhuzu Aphakathi Nethole vs. Amade

Amabhuzu aphakathi nendawo (cishe angama-25-30 cm ukuphakama) alungele ukusebenza ebhentshini lelabhorethri kanye nezikhathi ezimfushane lapho kuphuma uketshezi. Kulula ukuwagqoka nokuwakhumula, futhi alula. Amabhuzu amade (angaphezu kwama-40 cm, afinyelela okhalweni lwakho) alungele ukuchitheka koketshezi okukhulu, ukuma emachibini oketshezi, noma ukuya ezindaweni eziqinile. Ezindaweni zokulawula ubhubhane lapho phansi kunokungcola okubonakalayo, amabhuzu amade nawo angcono kakhulu. Amabhuzu e-biochemical avaliwe ngokuphelele anganamathela emilenzeni yezingubo zokuzivikela, futhi lokho kwenza uhlelo oluvaliwe ngokuphelele.

Izindinganiso Zesitifiketi Ongazethemba

Amaphepha okuphepha amabhuzu e-biochemical aqinile kakhulu kunamabhuzu ajwayelekile asefektri. Imithetho yaseYurophu: EN 13832 (amabhuzu avikela amakhemikhali) anohlobo 3, 2, noma 1 - lokho kusho ukumelana nokuchaphaza, ukumelana nokuxhumana isikhathi eside, kanye nokumelana nokucwiliswa ngokuphelele. EN 14126 (izingubo zokuvikela amagciwane) inokuhlolwa kokungena kwegciwane. Imithetho yase-US: ASTM F1671 kanye ne-F1670 (ukumelana namagciwane egazini); NFPA 1999 (umsebenzi wezokwelapha ophuthumayo). Ngakho-ke uma uthenga amabhuzu ezwe lakini noma ukuze uwathumele kwamanye amazwe, cela njalo umenzi imibiko yokuhlolwa yaleyo mithetho - hhayi nje uphawu "lwe-CE" olungacacile.

Iseluleko Sokulinganisa kanye Nokuthenga Ngobuningi

Amabhuzu e-biochemical avame ukugqokwa amasokisi amakhulu noma ngaphezulu kwamanye amabhuzu okuphepha ngaphakathi kwawo. Ngakho-ke kufanele u-ode ingxenye eyodwa kuya kweyodwa enkulu kunosayizi wezicathulo zakho ezijwayelekile. Uma uzizama, zenza sengathi wenza imisebenzi yangempela: hlala phansi, phakamisa umlenze wakho, bese ume isikhathi eside. Ukuze uthole ama-oda amakhulu, qala uthole amasampula ezisebenzi zakho zangaphambili ukuze uzame isonto lonke. Qaphela ukuthi iqakala ligoba kahle kangakanani, ukuthi ithole lilingana kanjani, nokuthi amabhuzu abangela ukukhuhlana yini ngesikhathi sokugqoka isikhathi eside. Cabanga nangendlela ozowahlanza ngayo. Amabhuzu aphinde asetshenziswe kumele aphathe ukuhlanza okuningi okubulala amagciwane ngaphandle kokuphuka.

Amabhuzu e-Biochemical alahlwayo vs. aphinde asetshenziswe

Amabhuzu e-biochemical alahlwayo avame ukwenziwa nge-PE, i-EVA, noma indwangu emboziwe engalukwanga. Alula, ashibhile, futhi alungele imisebenzi emifushane, ukugcinwa kwezimo eziphuthumayo, noma ukuya ezindaweni ezilawulwayo lapho ulahla khona amabhuzu ngemva kokusetshenziswa okukodwa. Okubi ukumelana nokubhoboza kahle, ukumelana nokuguguleka okuphansi, futhi adabuka kalula. Amabhuzu aphinde asetshenziswe enziwe ngerabha ejiyile noma ngezinto ezihlanganisiwe. Abiza kakhulu, kodwa aqinile futhi ahlala isikhathi eside, futhi angaphatha imijikelezo eminingi yokuhlanza. Alungele imisebenzi emide, izindawo ezinobungozi obukhulu, kanye namaqembu okutakula akhethekile. Lezi zinhlobo ezimbili azishintshi. Ngakho khetha ngokusekelwe ekutheni umsebenzi mude kangakanani, ukuthi ingozi iphakeme kangakanani, kanye nesabelomali sakho.

Uma ukhetha amabhuzu e-biochemical, asikho isikhala sokuxoxisana ngokuphepha nokulandela imithetho. Ungabheki nje intengo. Qondanisa ibhuzu nohlu lwakho lwamakhemikhali, izinga lakho lokuphepha kwe-bio, nokuthi uzosebenza isikhathi esingakanani. Uma udinga usizo ngemininingwane yakho, noma uma ufuna ikhambi elenziwe ngokwezifiso le-oda elikhulu, zizwe ukhululekile ukuxhumana nathi ngqo.
