Polyurethane adhesive glue

5. Kushandisa:

(1) pretreatment: pamusoro pekunamatira kunocheneswa.

(2) saizi: shandisa sawtooth scraper kuisa glue pamusoro peanonamira zvakaenzana, zvakare inogona kushandisa mechanic rolling coating, haigone kushandisa brashi bhurashi (glue viscosity yakakura), kubhurasha huwandu hunosvika 250g/m2, chaiyo zvichienderana mamiriro chaiwo anodzora kuwanda kweglue.

(3) composite: mushure mekunge guruu rinogona kuve rinobatanidza rinonamatira.

(4) mushure mekurapwa: nekuti guruu iyi inonamira nefuro, kana chinonamira chikaporeswa, guruu rinogona kuroverwa mukati megomba rekunamira, kuita basa rekumisa, kuwedzera simba rekubatanidza, uye rinofanira kudzvanywa. mushure mekuporeswa.

Features

Iyo ine hunhu hwekuita kwepamusoro, kuvakwa kuri nyore, kupupa mushure mekurapa, kusanyungudika uye kusanyungudika, yakakwirira uye yakaderera tembiricha kuramba.

Chikamu chekushandisa

Kugadzirwa kwemagonhi asingadziviri moto, magonhi anodzivirira kuba, magonhi epamba, midziyo inotonhora, uye zvakasiyana-siyana zvisingadziviriri moto uye zvinopisa zvinopisa (rock wool, ceramic wool, Ultra-fine glass wool, polystyrene foam plastic, nezvimwewo) inoshandiswawo zvakare. yekubatana.Kwesimbi kune simbi kunamatira.

Mirayiridzo

1. Nheyo yekurapa: Iyi inonamatira inhengo imwe-isina-solvent-isina adhesive, iyo inorapwa nehunyoro hunobatwa mumhepo uye pamusoro peiyo adherend.

2.Surface treatment of adherend: bvisa mafuta uye guruva pamusoro pekunamatira.Mavara emafuta akawandisa anogona kucheneswa neacetone kana xylene.Kana pasina tsvina yemafuta, hazvidiwi kuchenesa.Nguva, kana zvichidikanwa, pfapfaidza mhute shoma yemvura parubha pamusoro ne sprayer.

3.Glue coating: Shandisa zigzag scraper kuti ushandise glue pairi pamusoro peadherend.Mechanical glue inogonawo kuiswa, asi kubhurasha hakudiwi (girisi viscosity yakakura), uye huwandu hwekuputira hunenge 150-250g /㎡.Iyo yepamusoro yeadherend inogona kuderedzwa zvishoma, uye kushata kwepamusoro kunogona kuwedzera zvishoma, ndiko kuti, chero bedzi nzvimbo dzemabatiro maviri dzichisangana uye dzichikwanisa kubata glue zvakazara, iyo shoma iyo yekupfeka, zviri nani, nekuti iyo yakawanda glue inoshandiswa, iyo yakawanda Iyo hunyoro inobatwa pamusoro peiyo adherend inogumira, izvo zvinokanganisa nguva yekurapa.Kana huwandu hwenamo hwakaiswa huchidikanwa, mhute shoma yemvura inogona kupfapfaidzwa zvakakodzera.

4.compound: inogona kunama

5.Post-treatment: Nekuda kwekunamira kwefuro kwerabha iyi, kana iyo yekunamatira yakaporeswa, glue inogona kudonhedza pasi micropores yeadherend, iyo inobata basa rekusimbisa uye inowedzera simba rekubatanidza.Izvo zvinhu zvakabatanidzwa uye zvinogona kusunungurwa mushure mekurapa (kumanikidza kunenge 0.5kg-1kg / cm2).

6.Tool yekuchenesa inogona kushandisa ethyl acetate solvent.

Zvekungwaririra

1, Shandisa serrated spatula kune scraper, senge furati ndiro.Zvisinei, kana glue rikashandiswa zvakanyanya, hapazovi neglue yakasara pamusoro pekuputira.Kana iyo glue ikashandiswa zvishoma, glue ichava yakawandisa tsvina.Iyo zigzag scraper yakaoma sezvairi, uye glue yakasiiwa nesawtooth yakawanda.

2, Nzvimbo mbiri dzekubatanidza dzinofanira kusanganiswa dzinofanira kunama kune rimwe divi.

kuchengetedza nzira

Ichi chigadzirwa chinofanira kuchengetwa munzvimbo inotonhorera uye ine rima panguva yekuchengetedza.Kazhinji mumatura emukati, nguva yekuchengetedza igore rimwe.Mushure mekushandiswa kwega kweglue, dhiramu rine glue yakawandisa rinofanira kuvharwa uye kuchengetwa, uye iyo yepamusoro yeglue yemvura inosimbisa uye crust nekuda kwekupindira kwehunyoro.Kana ikasashandiswa kwenguva yakareba, inofanira kuvharwa ne nitrogen.
