Imikhombandlela emitsha yesicelo kunye neempawu zokuncamathelisa (2)

1. 1. Ukumelana nobushushu

Izinto zokuncamathelisa ubushushu obuphezulu be-Inorganic zidla ngokusetyenziswa kuluhlu lwe-1500-1750℃, ngelixa izincamathelisi ze-phosphate oxide zinoluhlu olubanzi lokumelana nobushushu kwaye zingasetyenziswa kuluhlu lwe-180-1400℃. Nangona kunjalo, ii-aggregates eziphambili ezisetyenziswa kwi-inorganic yokuncamathelisa ubushushu obuphezulu yisanti ye-zircon kunye nomhlaba okhanyelayo. Isanti ye-Zircon ixabisa kakhulu kwaye ixhomekeke ekuthengisweni kwamanye amazwe, kwaye umhlaba ochasayo kufuneka ufunyanwe ngeendleko zomhlaba, ezixabisa kakhulu. Ke ngoko, kunyanzelekile ukufumana iimveliso ezitshiphu nezifumaneka lula ukuze kuthathelwe indawo iiaggregates zemveli ukunciphisa iindleko zemveliso. Ezinye izinto zokuncamathelisa eziphilayo ziye zafumana ukumelana nobushushu obuphezulu ngokuguqulwa. Umzekelo, iglue ye-phenolic resin eguqulwe nge-B4C inokumelana nobushushu obuphezulu be-1500 ℃. Imfuno yemarike yokushisa - i-adhesives resistant ikhula rhoqo, ngoko olu hlobo lwe-adhesive lunamathuba ophuhliso olubanzi.

2. 2. Ungcoliseko oluphantsi

Njengoko imeko-bume yehlabathi isiya isiba mandundu, abantu ngokuthe ngcembe baqalisa ukusebenzisa ezinye iimveliso ezinobungani nokusingqongileyo. Nangona i-adhesives ayiloluhlu olukhulu lweemveliso zemichiza, umonakalo wabo kwimeko engqongileyo awunakuhoywa. Ezo zinto zincamathelayo zingenabungozi kokusingqongileyo ziya kuyekwa ngokuthe ngcembe. I-Polyethylene formaldehyde adhesive (eyaziwa ngokuba yi "107 glue") iqulethe i-formaldehyde yamahhala, eyingozi kwimpilo yabantu. Kudala yavalwa kumazwe athuthukileyo, kodwa kwilizwe lam, ngenxa yexabiso layo eliphantsi, isenesabelo esikhulu semarike. Nangona kunjalo, ukusetyenziswa kwayo kuye kwehla ngokuthe ngcembe kwaye kungekudala kuya kupheliswa ngokupheleleyo. Indlela yokuguqula izinto zokuncamathelisa ezingezizo ezendalo ngokwendalo zibe zincamathelisi ezinobungani nokusingqongileyo ngumsebenzi onyanzelekileyo.

3. 3. Unxulumano olungonakalisiyo

Iindlela eziphambili zokudibanisa izinto ziquka i-bolting, i-riveting, i-welding kunye ne-bonding. Nangona i-bolting kunye nobunye itekhnoloji inokufezekisa uqhagamshelo olukhawulezayo, ziya zonakalisa izixhobo ngenxa yomgodi okanye ukufudumeza kwendawo yezinto eziphathekayo, kwaye uxinzelelo lwexinzelelo alunakuthintelwa ngexesha lokusetyenziswa. Ngokwahlukileyo, itekhnoloji yokudibanisa ayiyo - itekhnoloji yoqhagamshelo eyonakalisayo, kwaye ngenxa yokuba i-interface ye-bonding ithwala umthwalo ngokubanzi, iphucula umthamo womthwalo kwaye yandisa ubomi benkonzo.

4. Ikhaphukhaphu

Ubuninzi be-adhesive buphantsi, ubukhulu becala phakathi kwe-0.9 kunye ne-2, malunga ne-20% ukuya kwi-25% yoxinaniso lwetsimbi okanye izinto ezingabonakaliyo, ngoko kunokunciphisa kakhulu ubunzima bezinto ezidibeneyo zokudibanisa.
