Kushanda kweFlame Retardants
Zvidziviriro zvemoto zvinodzivisa kana kunonoka kupararira kwemoto kuburikidza nekudzvinyirira maitiro emakemikari mumurazvo kana nekugadzirwa kwechidziviriro chekudzivirira pamusoro pechinhu.
Inogona kunge yakasanganiswa neyakagadzika zvinhu (yakawedzera murazvo retardants) kana makemikari akasungirirwa kwairi (reactive flame retardants).Mineral flame retardants inowanzowedzera asi organic komisheni inogona kuve inoshanda kana kuwedzera.
Kugadzira Fire-Retardant Adhesive
Moto une nhanho ina:
Kutanga
Kukura
Yakatsiga State, uye
Kuora
Kufananidza kweKudzikira Kupisa kweiyo Typical Thermoset Adhesive
Nevakasvika Mumatanho Akasiyana-siyana eMoto
Nyika imwe neimwe ine tembiricha yekushatisa inoenderana sezvakaratidzwa mumufananidzo.Mukugadzira chinonamira chinodzoreredza moto, vagadziri vanofanirwa kuisa simba ravo pakuburitsa tembiricha yekudzivirira padanho remoto rekushandisa:
● Mukugadzirwa kwemagetsi, semuenzaniso, chinonamira chinofanira kudzvanya chero katsika kechikamu chemagetsi kubata moto - kana kutanga - kana paine kukwira kunokonzerwa nekukanganisa kwekushisa.
● Kubatanidza mataira kana mapaneru, zvinonamira zvinoda kuramba kusungwa mukukura uye nhanho dzakatsiga dzemamiriro, kunyangwe kana yakanangana nemurazvo.
● Vanofanirawo kuderedza magasi ane chepfu uye utsi hunobudiswa.Zvivako zvinotakura mitoro zvingangosangana nematanho mana emoto.
Kuderedza Combustion Cycle
Kudzikamisa kutenderera kwekupisa, imwe kana akati wandei maitiro anokonzera moto anofanira kubviswa ne:
● Kubvisa mafuta anopisa, sekutonhodza
● Kugadzirwa kwechivharidzo chekupisa, sekupisa, nokudaro kubvisa mafuta nekudzikisa kupisa, kana
● Kudzima kuita kweketani mumurazvo, sekunge nekuwedzera akakodzera radical scavenger
Flame retardant additives inoita izvi nekuita kemikari uye/kana mumuviri muchikamu chakapfupikiswa (chakasimba) kana muchikamu chegasi nekupa rimwe remabasa anotevera:
●Charformers:Kazhinji phosphorus makomisheni, ayo anobvisa kabhoni peturu sosi uye inopa insulation layer inotarisana nekupisa kwemoto.Pane nzira mbiri dzekugadzira char:
Kudzokororwa kwemaitiro emakemikari anosanganisirwa mukuora achifarira maitiro anoburitsa kabhoni pane CO kana CO2 uye
Kuumbwa kwepamusoro pedenga rekudzivirira char
●Zvinopisa kupisa:Kazhinji mahydrates esimbi, akadai sealuminum trihydrate kana magnesium hydroxide, inobvisa kupisa nekubuda kwemvura kubva pachimiro chemurazvo wemoto.
●Zvinodzima moto:Kazhinji bromine- kana chlorine-based halogen masisitimu ayo anokanganisa maitiro mumurazvo.
● Synergists:Kazhinji antimony makomisheni, ayo anowedzera mashandiro emurazvo wemoto.
Kukosha kweFlame Retardants muKudzivirirwa kweMoto
Zvidziviriro zvemoto chikamu chakakosha chekudzivirira moto sezvo zvisingangodzikisi njodzi yekutanga kwemoto, asiwo yekupararira kwayo.Izvi zvinowedzera nguva yekupukunyuka uye, nekudaro, inochengetedza vanhu, midziyo, uye nharaunda.
Kune nzira dzakawanda dzekugadzira adhesive sechinhu chinodzivirira moto.Ngatinzwisise kurongeka kwemoto retardants zvakadzama.
Izvo zvinodikanwa zvekunamira zvinodzoreredza moto zviri kuwedzera uye kushandiswa kwavo kunowedzera kune akati wandei akasiyana indasitiri zvikamu mienzaniso inosanganisira aerospace, kuvaka, zvemagetsi uye zvifambiso zveveruzhinji (zvitima kunyanya).
1: Saka, imwe yenzira dziri pachena dzekuti usabatike murazvo / kusapisa kana, zviri nani zvakadaro, kudzivirira mirazvo - inodzivirira moto.
2: Inonamira haifanire kupa hutsi hwakanyanya kana muchetura.
3: Inonamira inoda kuchengetedza hunhu hwayo pakudziya kwakanyanya (ive neyakakwana yekudzivirira tembiricha sezvinobvira).
4: Yakaora inonamira zvinhu haifanire kuve ine chepfu ne-zvigadzirwa.
Zvinoita senge wakareba kuti uuye neanonamira anogona kuenderana nezvinodiwa izvi - uye panguva ino, viscosity, ruvara, kukurumidza kurapa uye yakasarudzika nzira yakaporeswa, gap kuzadzwa, kuita kwesimba, kupisa kwemhepo, uye kurongedza hazvisati zvamboitwa. zvakafungwa.Asi machemist ekusimudzira anonakidzwa nedambudziko rakanaka saka ZVINOITA!
Mitemo yezvakatipoteredza inowanzove yeindasitiri uye yakanangana nedunhu
Boka guru revanodzidzwa moto retardants rakaonekwa kuti rine hutano hwakanaka hwezvakatipoteredza uye hutano.Izvi ndezvi:
● Ammonium polyphosphate
● Aluminium diethylphosphinate
● Aluminium hydroxide
● Magnesium hydroxide
● Melamine polyphosphate
● Dihydrooxaphosphaphenanthrene

● 5VB (vertical plaque specimen) kupisa kunomira mu <60 seconds, pasina drips;muenzaniso unogona kugadzira gomba.
● 5VA sepamusoro asi isingabvumirwi kugadzira gomba.
Iwo maviri ekupedzisira kupatsanurwa angave ane bonde rakasungwa kwete sampuli yekunamira.
Kuyedzwa kwacho kuri nyore uye hakudi michina yakaomesesa, heino yekutanga bvunzo setup:
Zvinogona kuve zvine hunyengeri kuita iyi bvunzo pane mamwe anonamira chete.Kunyanya kune zvinonamira zvisingarape zvakanaka kunze kwejoint rakavharwa.Muchiitiko ichi, unogona kuedza chete pakati pemabonded substrates.Nekudaro, epoxy glue uye UV adhesives anogona kurapwa seyakasimba bvunzo sampuli.Wobva waisa bvunzo mushaya dzechigadziko chekusungirira.Chengetedza bhaketi rejecha pedyo, uye isu tinokurudzira zvakasimba kuita izvi pasi pekuchera kana muhutsi kabati.Usadzima chero maaramu ehutsi!Kunyanya ayo akabatana zvakananga kune emergency masevhisi.Bata mufananidzo pamoto uye nguva kuti zvinotora nguva yakareba sei kuti murazvo udzime.Tarisa kune chero madhiri pazasi (netariro, une tireyi inoraswa in situ; kana zvisina kudaro, bye-bye yakanaka worktop).
Adhesive chemist anosanganisa akati wandei ekuwedzera kugadzira zvinomisa moto zvinonamira - uye dzimwe nguva kudzima moto (kunyangwe chimiro ichi chakanyanya kuoma kuwana mazuvano nevagadziri vezvinhu vazhinji vava kukumbira maumbirwo asina halogen).
Zviwedzerwa zvezvinamira zvinodzivirira moto zvinosanganisira
● Mishonga inoumba char inobatsira kuderedza kupisa uye utsi uye kudzivirira zvinhu zviri pasi kuti risatsva.
● Heat absorbers, idzi dzinowanzoita simbi hydrates dzinobatsira kupa adhesive hukuru hunopisa hunopisa (kazhinji, zvigadziridzo zvinopisa moto zvinosarudzwa nokuda kwekushanda kwekugadzirisa kupisa kunopisa kunodiwa kunodiwa).
Iyo yekungwarira chiyero sezvo izvi zvinowedzera zvinokonzeresa kukanganiswa nezvimwe zvinonamira zvinhu zvakaita sesimba, rheology, kukurumidza kurapa, kuchinjika nezvimwe.
Pane musiyano here pakati pezvinonamira zvinodzivirira moto uye zvinonamira zvinomisa moto?
Ehe!Pane.Matemu ese ari maviri akasungwa nezvawo muchinyorwa, asi pamwe zvakanakisa kugadzirisa nyaya yacho.
Zvinamira zvinodzivirira moto
izvi zvinowanzova zvigadzirwa senge inorganic adhesive simende uye sealants.Hadzipise uye dzinoshingirira kutonhora kwakanyanya.Zvikumbiro zvemhando idzi dzezvigadzirwa zvinosanganisira, blast furnaces, hovhoni nezvimwewo. Havaite chero chinhu kumisa gungano kupisa.Asi vanoita basa guru rekubata mabheti ese ari kutsva pamwechete.
Fire retardant adhesives
Izvi zvinobatsira kudzima mirazvo uye kuderedza kupararira kwemoto.
Maindasitiri mazhinji anotsvaga aya marudzi ekunamira
● Zvemagetsi- yekugadzira potting uye encapsulating electronics, bonding heat sinks, circuit boards etc. Mhepo pfupi yemagetsi inogona kupisa moto nyore nyore.Asi maPCB ane zvigadziriso zvinodzivirira moto - zvinowanzokosha kuti zvinonamira zvinewo zvinhu izvi.
● Kuvaka- kupfekedza uye pasi (kunyanya munzvimbo dzevanhu) kazhinji kunofanirwa kunge kusingatsva uye kusungirirwa neadhesive inomisa moto.
● Zvifambiso zvevoruzhinji- ngoro dzechitima, mukati mebhazi, tram etc. Zvikumbiro zveFlame retardant adhesives zvinosanganisira bonding composite panels, flooring, uye zvimwe zvigadziriso uye fittings.Kwete chete zvinonamatira zvinobatsira kumisa kupararira kwemoto.Asi ivo vanopa aesthetic joint pasina kudiwa kweasingataridzike (uye rattly) mechanical fasteners.
● Ndege- sezvambotaurwa, zvinhu zvemukati zvekabhini zviri pasi pemitemo yakasimba.Zvinofanira kuva zvinodzivirira moto uye hazvizadze imba yacho nehutsi hutema panguva yemoto.
Mitemo uye Nzira dzekuedza dzeFlame Retardants
Miyero ine chekuita nekuyedzwa kwemoto yakanangana nekuona mashandiro echinhu zvine chekuita nemurazvo, utsi, uye chepfu (FST).Miedzo yakati wandei yakashandiswa zvakanyanya kuona kupokana kwezvinhu kune aya mamiriro.
