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 kugirango flame ikenera ibisabwa bya plastiki nibicuruzwa bya reberi, kugabanya umwanda w’umukungugu uterwa na retardants, flame retardant masterbatch yabayeho, kandi igira uruhare rukomeye kandi 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, gutatanya bigira uruhare runini cyane, ongeraho umubare runaka wabatatanye birashobora kuba byiza cyane mugutezimbere ikwirakwizwa rya flame retardant, kugirango byoroshye gutatanya kimwe muribwo buryo, kugirango hirindwe ko aglomeration ya retardant flame, ibyiza byo gukwirakwiza, kugira ngo ibicuruzwa bya flame bigabanye umuriro kugira ngo bikore neza, bityo ibizunguruka bigabanye umuriro, kugira ngo ibintu bishoboke kugira ngo umuriro ukorwe neza. mu ntangiriro.

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 ziterwa na flame ntishobora 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 umuriro wa extruder, igitutu cyo gusohora, kunoza imikorere yo gutunganya ibikoresho, hamwe no gusiga amavuta meza, kandi mugihe kimwe, birashobora kunoza neza ibyiyumvo byubuso bwibikoresho, hamwe nurwego runaka rworoshye kandi ntibigire ingaruka kumikorere ya flant ya retarda ya flant-retarda. ibisubizo bihanitse.

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