6. Isisombululo sokuhlamba intsimbi kunye nezinye iintsimbi, ii-agents ezidibeneyo kunye ne-welds;
7. I-Ceramics, iglasi kunye ne-enamel iyancibilika kunye ne-shading agents, ulusu oluluhlaza kunye ne-epidermal agents treatment of the industry tone;
8. Yenza abagqugquzeli be-phosphate kunyango olungaphezulu lwetsimbi emnyama ukuzinzisa isisombululo se-phosphorurative kunye nokuphucula ukusebenza kwe-membrane ye-phosphorus;
9. Njengokongeza kwimveliso yezinto zokutywinwa kunye neepakethi ze-brake, idlala indima ekwandeni kokumelana nokugqoka;
10. Njengezongezo kwikhonkrithi, phucula ukuxhathisa kwe-corrosion yekhonkrithi.
Ukulumkela:
1. Sebenzisa i-sodium fluoride ukulawula ngokungqongqo umthamo we-fluorine yonke imihla ukuthintela ukuveliswa kwetyhefu ye-fluoride;
2. Isisombululo sesodium fluoride okanye ijeli kufuneka ifakwe kwisitya seplastiki;
3. Izigulane, abafazi abakhulelweyo, abafazi abancancisayo, ukuthamba kwethambo kunye nokungaphumeleli kwezintso kwiindawo eziphezulu ze-fluoride akuvumelekanga.
Ukupakisha kunye nokugcinwa
Indlela yokuPakisha:iingxowa zeplastiki okanye ingxowa ezimbini zesikhumba zenkomo, imiphanda yebhodi ye-fiber yangaphandle, imiphanda yeplywood, imiphanda yebhodi enzima;imigqomo yeplastiki (eqinile) ngaphandle kweengxowa zeplastiki;imigqomo yeplastiki (ulwelo);Imigangatho emibini yeengxowa zeplastiki okanye enye -ingxowa yeplastiki umaleko ngaphandle kweengxowa, ukuluka iplastiki, ukuluka iingxowa zeplastiki, iingxowa zelatex;ingxowa yeplastiki ehlanganisiweyo iingxowa zeplastiki eziphothiweyo (ipolypropylene iingxowa ezintathu-kwi-nye, i-polyethylene iingxowa ezintathu, i-polypropylene ezimbini-kwi-ingxowa enye, i-polyethylene ezimbini-kwi-isinye isikhwama);iingxowa zeplastiki okanye iingxowa ezimbini zesikhumba zesikhumba ngaphandle kwebhokisi yomthi eqhelekileyo;ibhotile yeglasi yomsonto, isigqubuthelo sentsimbi cinezela ibhotile yeglasi, ibhotile yeplastiki okanye intsimbi yentsimbi (i-can) ibhokisi yeplanga eqhelekileyo;ibhotile yeglasi yentambo, ibhotile yeplastiki okanye i-tin-plated iplate yentsimbi ebhityileyo (i-can) Ibhokisi, ibhokisi ye-fiberboard okanye ibhokisi yeplywood.Ukupakishwa kwemveliso: 25kg/bag.
Izilumkiso zokugcina kunye nokuthutha:Ebudeni bothutho lukaloliwe, itafile yendibano yempahla eyingozi ifanele ifakwe ngokungqongqo ngokungqinelana neMithetho yoThutho lweeMpahla eziyingozi yeSebe likaLoliwe loLawulo lukaloliwe.Ngaphambi kokuthutha, jonga ukuba isikhongozeli sokupakisha sigqityiwe kwaye sitywinwe.Ngexesha lokuthutha, kufuneka kuqinisekiswe ukuba isitya akufanele sivuze, sidilike, siwe, okanye sonakaliswe.Akuvumelekanga ngokungqongqo ukudibanisa ne-asidi, i-oxidant, ukutya kunye nezongezo zokutya.Ngexesha lothutho, izithuthi zothutho kufuneka zixhotyiswe ngezixhobo zonyango olungxamisekileyo lokuvuza.Ngexesha lokuthutha, ukukhanya kwelanga kunye nemvula kufuneka kuvezwe ukukhusela ukushisa okuphezulu.Gcina kwindawo epholileyo, eyomileyo, nengena umoya.Ubushushu bethala leencwadi alidluli kuma-30 ° C, kwaye ukufuma okuhambelanayo akudluli kwi-80%.Ukupakisha kunye nokutywinwa.Gcina ngokwahlukileyo kwi-asidi kunye neekhemikhali ezidliwayo, kugweme ukuxuba.Indawo yokugcina iya kuba nesixhobo esifanelekileyo sokuqulatha ukuvuza.Gcoba ngokungqongqo inkqubo yolawulo “yokuphinda kabini” kwezinto ezinetyhefu.
