Nigute ushobora kunoza ikwirakwizwa rya flame retardants

Hamwe nogukoresha kwinshi ibikoresho bya polymer nibicuruzwa bya elegitoroniki mubuzima bwa buri munsi, umubare wumuriro nawo uragenda wiyongera, kandi ingaruka izana irateye ubwoba kurushaho. Imikorere ya flame retardant yibikoresho bya polymer yarushijeho kuba ingenzi, ni murwego rwo kugera kubisabwa bya flame retardant ibisabwa bya plastiki nibicuruzwa bya reberi, kugabanya umwanda w’umukungugu uterwa na retardants, flame retardant masterbatch yabayeho, kandi ikina byingenzi. n'uruhare rukomeye muguhindura ibicuruzwa byanyuma.

Flame retardant masterbatch ikorwa hakurikijwe formulaire yumvikana, binyuze muburyo bwo guhuza ibinyabuzima bya flame retardant, lubricant dispersant hamwe nuwitwara, binyuze mu gutunganya neza, kuvanga, guhuza hamwe no gukuramo granulation. Muri ibi, abatatanye bafite uruhare runini cyane, ongeraho igice runaka cyabatatanye birashobora kuba byiza cyane mugutezimbere ikwirakwizwa rya flame retardant, kuburyo byoroshye gutatanya kimwe muribwo buryo, kugirango wirinde ko agglomeration yumuriro utinda, ibyiza byo gukwirakwiza, kugirango kugirango molekules zidindiza flame zigire ingaruka nziza zo gukumira flame, bityo bizamura imikorere yumuriro wa plastike, reberi, umuriro uzanigwa umunwa hakiri kare.

Nyamara, mubikorwa, plastike nyinshi nibice bya reberi birimo flame-retardant ibice ntibishobora gukora imitungo ya flame-retardant bitewe no gukwirakwiza kudahuza flame-retardant mubikoresho mumuriro, bikaviramo umuriro mwinshi nigihombo gikomeye.

Mu rwego rwo guteza imbere ikwirakwizwa rimwe rya flame retardants cyangwa flame retardant masterbatch mugikorwa cyo kubumba ibicuruzwa, kugabanya ikibazo cyo gutatana kuringaniye guterwa ningaruka zumuriro ntizishobora gukoreshwa neza, nibindi, kandi bikazamura ireme ryibicuruzwa byangiza umuriro, SILIKE yateje imbere silicone yongeyeho SILIMER hyperdispersant.

SILIMER ni ubwoko bwa tri-block copolymerized yahinduwe siloxane igizwe na polysiloxane, amatsinda ya polar hamwe nitsinda rinini rya karubone. Ibice by'urunigi rwa polysiloxane birashobora kugira uruhare runini rwo kwigunga hagati ya molekile ya flame retardant munsi ya shear ya mashini, bikarinda icyegeranyo cya kabiri cya molekile ya retardant; ibice by'itsinda rya polarike bifite aho bihurira na flame retardant, bigira uruhare rwo guhuza; ibice birebire bya karubone bifite aho bihurira cyane nibikoresho fatizo.

Uru ruhererekane rwibicuruzwa bikwiranye nubushuhe busanzwe bwa termoplastique, TPE, TPU nandi mashanyarazi ya elastomeri, kandi birashobora kunoza ubwuzuzanye hagati ya pigment / yuzuza ifu / ifu ikora na sisitemu ya resin, kandi bikagumya gutatanya ifu ihamye.

Muri icyo gihe, irashobora kandi kugabanya ubukonje bwashonga, kugabanya itara rya extruder, igitutu cyo gukuramo, kunoza imikorere yo gutunganya ibikoresho, hamwe no gusiga neza, kandi mugihe kimwe birashobora kunoza neza ibyiyumvo bya ubuso bwibikoresho, hamwe nurwego runaka rworoshye kandi ntibigira ingaruka kumiterere yibikoresho, ni uguteza imbere gukwirakwiza ibice bigize flame-retardant kugirango biteze imbere ingaruka mbi yibicuruzwa byanyuma kugirango bitange umukino wuzuye murwego rwo hejuru -ibisubizo byuzuye.

Mubyongeyeho, uruhererekane rwibicuruzwa ntabwo rukwiranye gusa na flame retardant masterbatch, ariko kandi no muburyo bwo gushushanya amabara cyangwa kwibanda cyane kubikoresho mbere.
