Phau Ntawv Qhia Yuav Khau looj Biochemical: Yuav Ua Li Cas Xaiv Rau Cov Chaw Tsim Tshuaj, Chaw Soj Ntsuam, Kev Tswj Kab Mob Sib Kis, thiab Kev Kho Dej Pov Tseg

Phau Ntawv Qhia Yuav Khau looj Biochemical: Yuav Ua Li Cas Xaiv Rau Cov Chaw Tsim Tshuaj, Chaw Soj Ntsuam, Kev Tswj Kab Mob Sib Kis, thiab Kev Kho Dej Pov Tseg

Hauv cov chaw tsim tshuaj lom neeg, cov chaw kuaj mob, cov chaw tswj kev sib kis, thiab cov chaw kho dej khib nyiab, cov neeg ua haujlwm tsis ntsib cov av nkos thiab dej ib txwm muaj. Lawv ntsib cov kua qaub muaj zog, cov alkali muaj zog, cov kab mob, cov kab mob me me, thiab cov tshuaj lom. Cov khau looj nag ib txwm muaj lossis cov khau tiv thaiv kev nyab xeeb hauv Hoobkas raug cov tshuaj lom neeg noj lossis tsis tuaj yeem tiv thaiv cov kab mob kom tsis txhob nkag mus. Yog li cov khau biochemical tsis yog cov khoom siv kev nyab xeeb ib txwm muaj. Lawv yog cov khoom siv kawg tiv thaiv kev phom sij ntawm tshuaj lom neeg thiab kab mob. Phau ntawv qhia no qhia koj yuav ua li cas xaiv raws li koj txoj haujlwm, cov yam ntxwv tseem ceeb uas yuav tsum nrhiav, koj xav tau khau siab npaum li cas, cov ntawv pov thawj kev nyab xeeb twg yuav tsum xyuas, yuav ua li cas xaiv qhov loj me, yuav ua li cas yuav ntau, thiab qhov sib txawv ntawm cov khau pov tseg thiab cov khau siv tau dua.

Xaiv los ntawm Xwm Txheej: Plaub Qhov Chaw Ib Txwm Muaj, Cov Kev Xav Tau Sib Txawv

Cov chaw ua haujlwm tshuaj lom neeg thiab chaw kuaj mob feem ntau muaj cov kua qaub muaj zog xws li sulfuric acid, hydrofluoric acid, thiab cov organic solvents. Thaum koj xaiv khau rau cov chaw no, tsom mus rau kev tiv thaiv acid/alkali thiab kev tiv thaiv permeation. Cov roj hmab yuav tsum tau ntsuas rau cov tshuaj tshwj xeeb thiab lawv muaj zog npaum li cas, tsis yog tsuas yog daim ntawv lo "tiv taus tshuaj lom neeg" tsis meej. Rau kev tswj kev sib kis thiab chaw tua kab mob, qhov txaus ntshai tseem ceeb yog cov kab mob, cov kab mob me me, thiab cov tshuaj tua kab mob. Yog li cov khau yuav tsum muaj daim ntawv pov thawj tiv thaiv kab mob, zoo li ASTM F1671 rau kev nkag mus rau hauv cov kab mob. Lawv kuj yuav tsum tiv taus cov tshuaj tua kab mob chlorine, peracetic acid, thiab lwm yam tshuaj ntxuav muaj zog. Rau cov chaw kho dej khib nyiab, qhov txaus ntshai yog sib xyaw: cov pa roj corrosive (xws li hydrogen sulfide), cov kab mob hauv cov av nkos, thiab cov khoom ntse ntawm cov khib nyiab. Yog li cov khau xav tau kev tiv thaiv tshuaj lom neeg, kev tiv thaiv kev tho, kev tiv thaiv kev plam, thiab kev tiv thaiv permeation. Cov khau roj hmab siab, tsis muaj qhov sib txuas, zoo tshaj plaws.

Cov Qauv Tseem Ceeb Yuav Tsum Tau Tshawb Xyuas: Kev Tiv Thaiv Acid/Alkali, Kev Tiv Thaiv Kev Nkag, Kev Tiv Thaiv Kev Cuam Tshuam, Kev Tiv Thaiv Kev Tho

Tag nrho plaub yam no tseem ceeb heev. Rau kev tiv taus kua qaub/alkali, nrhiav cov ntaub ntawv xeem tshwj xeeb. Qhov ntawd txhais tau tias lub khau raj tuaj yeem nyob ntev npaum li cas hauv cov tshuaj uas muaj zog tshaj 30% yam tsis muaj o, mos, lossis tawg. Kev tiv taus permeation txhais tau tias ob qho tib si kua thiab roj tsis tuaj yeem hla dhau, suav nrog cov pa phem uas yog cov molecules me me. Cov kev xeem nruj tshaj plaws siv cov pa roj tracer lossis cov cim radioactive. Kev tiv thaiv kev cuam tshuam thiab kev tho tsis yog rau txhua lub khau biochemical, tab sis lawv xav tau hauv cov chaw teeb tsa Hoobkas, zoo li thaum koj ua kev saib xyuas hauv lub Hoobkas tshuaj lossis kov cov khib nyiab txaus ntshai. Lub hau hlau lossis cov khoom sib xyaw thiab Kevlar qhov tho nruab nrab tiv thaiv cov khoom poob thiab cov ntsia hlau ntse.

Kev Xaiv Qhov Siab Ntawm Lub Ncej: Nruab Nrab Lub Cev vs. Khau Siab

Khau looj plab nruab nrab (kwv yees li 25 30 cm siab) zoo rau kev ua haujlwm hauv chav kuaj thiab rau lub sijhawm luv luv thaum cov kua dej txaws. Lawv yooj yim hnav thiab tshem tawm, thiab lawv sib dua. Khau siab (dhau 40 cm, txog koj lub duav) zoo rau cov kua dej loj nchuav, sawv hauv cov pas dej, lossis mus rau hauv qhov chaw nqaim. Rau cov chaw tswj kev sib kis kab mob uas hauv pem teb muaj av pom, khau siab kuj zoo tshaj plaws. Cov khau biochemical uas kaw tag nrho tuaj yeem txuas rau ob txhais ceg ntawm cov khaub ncaws tiv thaiv, thiab qhov ntawd ua rau lub kaw lus kaw tag nrho.

Cov Qauv Ntawv Pov Thawj Koj Ntseeg Tau

Cov ntawv kev nyab xeeb rau cov khau biochemical yog nruj dua li cov khau Hoobkas ib txwm muaj. Cov cai European: EN 13832 (khau uas tiv thaiv cov tshuaj lom neeg) nrog Hom 3, 2, lossis 1 - qhov ntawd txhais tau tias tiv taus dej txaws, tiv taus kev sib cuag ntev, thiab tiv taus kev nkag mus tag nrho. EN 14126 (khaub ncaws tiv thaiv cov kab mob) muaj kev sim nkag mus rau hauv kab mob. Cov cai ntawm Tebchaws Meskas: ASTM F1671 thiab F1670 (tiv taus cov kab mob hauv cov ntshav); NFPA 1999 (kev ua haujlwm kho mob thaum muaj xwm txheej ceev). Yog li thaum koj yuav khau rau koj lub tebchaws lossis rau kev xa tawm, ib txwm nug tus tsim khoom rau cov ntawv xeem rau cov cai ntawd - tsis yog tsuas yog lub cim "CE" tsis meej.

Kev Qhia Txog Qhov Loj thiab Kev Yuav Khoom Ntau

Cov khau looj biochemical feem ntau hnav nrog cov thom khwm tuab lossis hla lwm cov khau tiv thaiv kev nyab xeeb hauv lawv. Yog li koj yuav tsum xaj ib nrab mus rau ib qhov loj dua li koj cov khau ib txwm. Thaum koj sim lawv, ua txuj ua cov haujlwm tiag tiag: squat, tsa koj ceg, thiab sawv ntev. Rau cov xaj loj, ua ntej kom tau cov qauv rau koj cov neeg ua haujlwm pem hauv ntej sim rau ib lub lim tiam. Saib seb pob luj taws puas khoov zoo, lub plab hlaub haum li cas, thiab yog tias cov khau ua rau khaus thaum hnav ntev. Tsis tas li ntawd xav txog seb koj yuav ntxuav lawv li cas. Cov khau siv rov qab tau yuav tsum tuav ntau yam kev ntxuav tshuaj tua kab mob yam tsis tawg.

Khau looj biochemical uas siv pov tseg piv rau Khau looj biochemical uas siv tau dua

Cov khau biochemical pov tseg feem ntau yog ua los ntawm PE, EVA, lossis cov ntaub coated uas tsis yog woven. Lawv yog lub teeb, pheej yig, thiab zoo rau cov haujlwm luv luv, cov khoom siv thaum muaj xwm txheej ceev, lossis mus rau hauv thaj chaw tswj hwm uas koj pov tseg cov khau tom qab siv ib zaug. Qhov tsis zoo yog qhov tsis kam rau qhov tho, tsis kam hnav, thiab lawv yooj yim dua. Cov khau rov siv tau yog ua los ntawm cov roj hmab tuab lossis cov ntaub ntawv txheej. Lawv kim dua, tab sis lawv ruaj khov thiab siv tau ntev, thiab lawv tuaj yeem tswj tau ntau lub voj voog ntxuav. Lawv zoo rau cov haujlwm ntev, thaj chaw muaj kev pheej hmoo siab, thiab cov pab pawg cawm neeg tshwj xeeb. Ob hom tsis hloov ib leeg. Yog li xaiv raws li ntev npaum li cas txoj haujlwm, qhov kev pheej hmoo siab npaum li cas, thiab koj cov peev nyiaj.Thaum koj xaiv cov khau looj biochemical, tsis muaj chaw los sib tham txog kev nyab xeeb thiab kev ua raws li cov cai. Tsis txhob saib tus nqi xwb. Sib phim cov khau looj kom haum rau koj daim ntawv teev cov tshuaj lom neeg, koj qib kev nyab xeeb biosafety, thiab koj yuav ua haujlwm ntev npaum li cas. Yog tias koj xav tau kev pab nrog cov specs rau koj tus kheej, lossis yog tias koj xav tau kev daws teeb meem tshwj xeeb rau kev txiav txim loj, xav tiv tauj peb ncaj qha.
