Shiinaha Caustic Soodhaha tayada ugu fiican
Soodhaha Caustic, oo sidoo kale loo yaqaan lye amasodium hydroxide, waa kiimiko muhiim ah oo loo isticmaalo warshado kala duwan, laga bilaabo samaynta saabuunta ilaa daaweynta biyaha. Soodhaha caustic waxa ay leedahay adeegsi balaadhan oo kala duwan, sidaa awgeed waa muhiim in la hubiyo gaadiid badbaado leh, gaar ahaan marka la maaraynayo foomamka sida soodhaha caustic cad iyo soodhaha caustic soodhaha ah. Maareynta saxda ah iyo baakaduhu waa lagama maarmaan si looga hortago shilalka loona hubiyo daacadnimada alaabta inta lagu jiro gaadiidka.
Durbaannada birta ah ayaa ah habka la door bidayo ee lagu rari karo soodhaha caustic, gaar ahaan marka loo isticmaalo baabuurta furan ee gaadiidka tareenka. Baakadu waa inay noqotaa mid dhamaystiran oo si ammaan ah loo raray si looga hortago wax daadanaya ama daadanaya. Durbaanadu waa inay noqdaan qoyaan iyo roobka si ay uga ilaaliyaan soodhaha caustic ee arrimaha deegaanka ee saameeya tayada.
Ka hor inta aan la dhoofin, waxaa muhiim ah in la eego baakadaha calaamadaha burburka. Haddii durbaannada birta ahi ay muujiyaan calaamadaha miridhku, dildilaaca ama godadka, waa in isla markiiba la beddelaa. Weel kasta oo ka muuqda calaamadaha jeexjeexyada biyaha ayaa soo bandhigaya khatar weyn waana in wax laga qabto ka hor inta aan la rarin. Xaaladaha qaarkood, weelasha burburay waxaa lagu hagaajin karaa alxanka, laakiin tani waa in la sameeyaa kaliya haddii daacadnimada weelka la dammaanad qaadi karo.
Intaa waxaa dheer, soodhaha caustic waa inaan waligood lagu qasin walxaha guban ama guban kara, aashitada, ama kiimikooyinka cuntada inta lagu jiro gaadiidka. Taxadardani waa lama huraan si looga hortago fal-celin kiimikaad oo khatar ah inay dhacaan una horseedaan xaalado khatar ah.
Si loo sii wanaajiyo badbaadada, gaadiidka daabula waa in lagu qalabeeyaa qalabka waxka qabashada xaaladaha degdega ah ee daadanaya. Tani waxay hubinaysaa in haddii daadad dhacdo, tallaabo degdeg ah ayaa la qaadi karaa si loo yareeyo waxyeellada ka iman karta deegaanka ama shaqaalaha.
Marka la soo koobo, ha ahaato mid dareere ah ama qaab jajab ah, si badbaado leh u qaadida soodhaha caustic waxay u baahan tahay baakad taxadar leh, kormeer, iyo u hogaansanaan nidaamka badbaadada. Markaan raacno dhaqamadan ugu wanaagsan, waxaan xaqiijin karnaa gaadiidka badbaadada leh ee kiimikadaan muhiimka ah anagoo ilaalinayna shaqaalaheena iyo deegaanka.

isticmaalka
Sodium hydroxide waxay leedahay USES badan oo loo isticmaalo samaynta waraaqaha, saabuunta, dheeha, rayon, aluminium, sifaynta batroolka, dhamaystirka suufka, nadiifinta taarikada dhuxusha, wakiilka nadiifinta alkaline ee daaweynta biyaha iyo habaynta cuntada, warshadaynta alwaax iyo warshadaynta. Faahfaahinta waa sida soo socota:
Warshadaha saabuunta
loo isticmaalo daawaynta biyaha sida wakiilka iska-qaboojinta ogsijiinta.
loo isticmaalo warshadaha saxarka iyo waraaqaha.
loo isticmaalo warshadaha saxarka iyo waraaqaha.
loo isticmaalo warshadaha dharka sida bleaching, sida sunta-saarid iyo wakiilka dekloriinta.
