Nyob rau lub caij nyoog uas cov kev cai tswjfwm kev nyab xeeb nruj zuj zus thiab kev tiv thaiv hluav taws yog qhov tseem ceeb hauv kev tsim kho, kev tsim khoom, thiab kev siv hluav taws xob, kev xaiv cov nplaum uas tiv taus hluav taws yog qhov kev txiav txim siab tseem ceeb heev.Cov kua nplaum uas tiv taus hluav taws kub heev"Tsis yog ib yam khoom xwb tab sis yog ib pawg ntawm cov nplaum ua tau zoo uas tsim los tswj kev ruaj khov thiab kev sib txuas hauv qab qhov kub thiab nplaim taws ncaj qha. Tsab xov xwm kev tshaj lij 1800-lo lus no muab cov txheej txheem rau cov engineers, cov neeg qhia tshwj xeeb, thiab cov tub ceev xwm kev nyab xeeb los soj ntsuam thiab xaiv cov nplaum hluav taws uas tsim nyog tshaj plaws rau lawv daim ntawv thov tshwj xeeb. Peb yuav txiav txim siab cov yam ntxwv tseem ceeb suav nrog kev ntsuas hluav taws, cov tshuaj lom neeg sib xyaw, kev sib raug zoo ntawm cov khoom siv, ib puag ncig daim ntawv thov, thiab kev ua tau zoo mus sij hawm ntev.

Nkag Siab Txog "Fireproof" Hauv Cov Nplaum: Cov Lus Txhais Thiab Cov Qauv

Ua ntej pib xaiv, ib tug yuav tsum nkag siab tias "fireproof" txhais li cas tiag tiag hauv cov ntsiab lus ntawm cov nplaum. Tsis muaj cov nplaum twg uas tsis puas tsuaj tag nrho rau hluav taws mus ib txhis. Lo lus feem ntau txhais tau tias cov nplaum uas muaj hluav taws zoo heev. tsis kam, characterized los ntawm:

• Kub Kub Kub: Qhov kub uas cov nplaum nws tus kheej pib hlawv.
• Kev Sib Kis Hluav Taws Tsawg: Lub peev xwm los tiv taus qhov kev nthuav dav ntawm nplaim taws hla nws qhov chaw.
• Kev Tso Tawm Kub Txwv: Tus nqi thiab tag nrho cov cua sov uas tso tawm thaum lub sijhawm hlawv.
• Kev Haus Luam Yeeb Tsawg thiab Kev Lom Zem: Tseem ceeb heev rau kev nyab xeeb ntawm cov neeg nyob hauv, vim tias cov pa luam yeeb thiab cov pa lom yog cov ua rau muaj kev tuag ntau tshaj plaws los ntawm hluav taws.
• Kev Ncaj Ncees ntawm Cov Qauv Hauv Qab Kub: Cov nplaum muaj peev xwm khaws tau ib feem tseem ceeb ntawm nws lub zog sib txuas thiab qhov ruaj khov ntawm qhov kub siab, txawm tias tom qab cov resin matrix tau hlawv lawm los xij.

Cov khoom no raug ntsuas los ntawm cov qauv thoob ntiaj teb. Cov ntawv pov thawj tseem ceeb uas yuav tsum nrhiav suav nrog:

• Kev lag luam tawm: Yog tias muaj halogenated, nws yuav tso tau cov pa phem ntau dua (HCN, CO). Kev ua tau zoo ntawm qhov kub siab heev tsuas yog txwv piv rau cov silicones lossis inorganics.
• Zoo Tshaj Plaws Rau: Kev sib txuas cov khoom sib xyaw, cov yas, thiab ntoo hauv kev thauj mus los thiab kev tsim kho qhov twg xav tau kev ywj pheej thiab kev txhaws qhov sib txawv.

1. Cyanoacrylates ("Super Glues") thiab Acrylics

• Kev Ua Haujlwm Hluav Taws Xob: Feem ntau tsis zoo. Cov no yog cov organic thiab flammable. Txawm hais tias cov qib tshwj xeeb nrog cov khoom ntxiv uas tiv taus hluav taws muaj nyob, lawv feem ntau tsis raug txiav txim siab rau cov ntawv thov "super fireproof". Lawv tuaj yeem siv rau hauv cov ntawv cog lus me me, tsis tseem ceeb hauv cov khoom sib dhos loj dua uas tiv thaiv hluav taws.

 

 

Lub Txheej Txheem Xaiv: Ib Kauj Ruam-rau-Kauj Ruam Txheej Txheem

Kev xaiv cov nplaum zoo yuav tsum tau muaj kev tshuaj xyuas kom meej txog qhov xav tau ntawm koj daim ntawv thov.
