Hot melt adhesive imhando yekunamira epurasitiki. Mukati meimwe tembiricha yemhando, chimiro chayo chemuviri chinoshanduka nekushanduka kwetembiricha, nepo makemikari ayo anoramba asina kuchinjika. Haina chepfu uye haina kunaka. Icho chigadzirwa chemakemikari chinoshamwaridzana zvakatipoteredza.
Nekuti chigadzirwa pachacho chakasimba, chakanakira kurongedza, kutakura uye kuchengetedza, solvent-isina, kusvibiswa-isina uye isina chepfu; Uye zvakanakira nyore kugadzira maitiro uye yakakwirira bonding simba.

Pe wakisi yekunamira inopisa inonyungudika ine kuderera kwehuremu hwekudzikira, kuderera kwemafuta emukati uye kuoma kwakanyanya.

Hot melt adhesive ine akawanda uye akawanda marudzi uye mashandisiro. Inogona kubatanidza matehwe, girazi, simbi, huni, mapurasitiki emikwende, kurapwa, machira, nezvimwewo inoshandiswa zvakanyanya mukuvaka, machira, zvemagetsi, kurapwa, mota uye mamwe maindasitiri.
Izvo zvakajairwa zvehot melt adhesive ndeye organic synthetic zvinhu. Izvo zvakajairika zvikamu zvinosanganisira zvinotevera zvinhu: chikuru zvinhu, tackifier, softener, filler, antioxidant uye regulator.
Iyo huru zvinhu zvinonyanya kuita basa rekuita musimba rekubatanidza, kupisa kupisa, kuomarara uye nepakati kuramba kwekupisa-kunyunguduka kunama. Inowanzo kuumbwa imwe kana akati wandei akakwira mapolymers. Softener inoita kuti kupisa kunyungudika kunamatira kuve nyore kugadzira uye kugadzirisa. Mafirita anowanzo shandisa inorganic zvinhu izvo zvisingaite nezvikamu kuwedzera viscosity yecolloids uye kunatsiridza mhedzisiro yekupikisa uye simba remagetsi. MaAntioxidants anowedzera hupenyu hwesevhisi uye kuramba kupisa kweanonamatira anonyunguduka.
Kuonekwa uye chimiro chekunamatira kunopisa kunopisa kunosiyana zvichienderana nezvinangwa zvakasiyana:
1. Kupisa kunyunguduka kwakanamatira tsvimbo:
Iyo yakasimba yakanamatira inogadzirwa neEVA sechinhu chikuru, tackifier uye zvimwe zvikamu. Iine maitiro ekukurumidza kunamatira, simba rakakwirira, kuramba kuchembera, hapana chepfu uye kugadzikana kwakanaka kwekupisa. Inogona kushandiswa kuita huni, mapurasitiki, kurongedza uye zvimwe zvakaomesesa zvinonamira, uye inogona kushandiswa zvakanyanya mumafekitori nemhuri. Hot melt glue stick rinowanzo shandiswa nehot melt glue pfuti.

2. Hot melt particles:
Hot melt rubber particles ipurasitiki inonamira zvigadzirwa. Mukati meimwe tembiricha yemhando, mamiriro emuviri ekupisa anonyungudusa rubber particles anoshanduka nekushanduka kwetembiricha, ukuwo makemikari anoramba asina kushanduka. Hot melt rubber particles haina chepfu uye haina kunaka. Izvo zvakatipoteredza zvine hushamwari glue zvigadzirwa. Hot melt rubber particles inogona kushandiswa mukurongedza mune ese mafambiro ehupenyu. Zvimedu zvinonamira zvinonyunguduka zvinoshandiswa kunyungudutsa chinonamira chinopisa chinonyunguduka kuburikidza nekupisa muchina unopisa unonyunguduka wekunamatira, uye glue mushure mekunyunguduka inova mvura. Iyo inopisa-yakanyunguduka yakanamatira inotumirwa pamusoro pechinhu chakasungirirwa kuburikidza ne-hot-melt adhesive pombi uye inopisa-yakanyunguduka yakanamatira pfuti yemuchina wekunamatira unopisa, uye kusungirirwa kunopedzwa mushure mokunge chigadziro chinopisa chinopisa chatonhora.
3. Kupisa kunyunguduka firimu:
Kupisa kunyunguduka kwakanamatira firimu imhando yechigadzirwa chemufirimu chine bepa rekuburitsa kana pasina pepa rekuburitsa, iro rinogona kushandiswa nguva dzose kana zvishoma nezvishoma. Inogona kushandiswa zvakanyanya kubatanidza marudzi ese emachira, mapepa, polymer zvinhu uye simbi.
Inopisa inonyungudika inonamira firimu inogona kukamurwa kuita thermoplastic uye thermosetting zvinoenderana nemaitiro ayo ekushandisa. Iine maitiro anotevera:
(1) Iine yakanaka inopindirana uye yunifomu yekubatanidza ukobvu;
(2) isina Solvent, iri nyore kugadzirisa;
(3) Kunamatira kwakanaka kune zvinhu zvakawanda;
(4) Ukobvu i 0.1-0.203mm uye ruvara runopenya / amber;
(5) Inogona kubayiwa mune chaiyo maumbirwo uye saizi, uye inokodzera yakachena bhuku kana otomatiki application.
Chigadzirwa chekushandisa: inogona kubatanidza simbi, plastiki, pepa, huni, ceramics, machira uye zvimwe zvinhu, uye inogonawo kuwana mhedzisiro yakanaka pamusoro pezvinhu zvisina kuenzana.
4. Hot melt pressure sensitive adhesive:
Hot melt pressure-sensitive adhesive is adhesive based on thermoplastic polymer. Iine maitiro maviri ekupisa kunyunguduka uye kushushikana-kunzwa. Inogona kuputirwa mumamiriro ekunyunguduka. Mushure mekutonhodza, inogona kusungirirwa nekukurumidza nekushandisa kudzvanywa kwechiedza. Panguva imwecheteyo, haigone kusvibisa zviri nyore pamusoro peiyo adherend.

Iyo yakajairika kuumbwa kwe-hot-melt pressure-sensitive adhesive ndeye: polymer elastomer, yakadai seSIS, SBS, SEBS, SEPS, nezvimwewo, pamwe netackifier, plasticizer, filler uye antioxidant. Iyo inonyanya kupisa thermoplastic elastomer, kureva SBS uye SIS thermoplastic elastomer. SBS, inozivikanwawo se thermoplastic styrene butadiene rubber, inonzi thermoplastic elastomer. SBS ine yakanaka solubility uye inoenderana nemapolymer mazhinji. Kuwedzera resin uye tackifier kunogona kuderedza kunyunguduka kwayo. Inonyatsokodzera kugadzirira hot-melt pressure-sensitive adhesive. SIS ndeye block copolymer ye styrene uye isoprene. Iyo ine yakaderera modulus, yakaderera mhinduro viscosity uye melt viscosity uye yakanaka processability. Nekuti SIS yepakati block polyisoprene ine padivi cheni methyl muchimiro, ine kubatana kwakanaka, kunamatira kwakanakisa uye kuenderana kwakanaka nezvimwe zvinowedzera, SIS inopisa inonyunguduka inomanikidza inonamira inonamira iri nani yekutanga kunamatira pane SBS inopisa kunyunguduka kumanikidza inonamira inonamatira.
Tackifying resin chimwe chinhu chakakosha chekumanikidza-sensitive adhesive kunze kweiyo huru elastic body. Basa rayo guru ndere kupa pressure-sensitive adhesive inodiwa viscosity. Imhaka yekuti tackifying resin inosanganiswa mune rabha elastomer iyo yekusanganisa system inoburitsa inodiwa yekutanga viscosity uye kunamatira kumusoro kweiyo yakasungwa zvinhu.
Anowanzo shandiswa tackifiers anogona kupatsanurwa muzvikamu zviviri
: rosin, rosin zvinobva (hydrogenation, disproportionation, polymerization, esterification)
Natural resin terpene akatevedzana: terpene resin (α－ Terpene β－ Terpene), terpene phenolic resin, anonhuwirira resinified terpene , hydrogenated terpene resin.
