Tsananguro yeChigadzirwa

RN yedu, yakagadzirwa semushonga wekuporesa/kusanganisa glue uchishandisa hydroxyl polyurethane, rabha dzechisikigo uye dzekugadzira. RN inonhuhwirira NCO isocyanate, haina ruvara uye haina kusimba zvakanyanya. Nekuda kweRN ine anti-yellowing yakanaka, inonyanya kukodzera kudiwa kweglue polyurethane ine ruvara rwakareruka. Nekuti solvent iyi iethyl acetate, RN inogona kushandiswa munyika idzodzo uko kushandiswa kwemethylene chloride kwakaganhurirwa.

Zvimiro zveChigadzirwa

Firimu refirimu rinonamira uye rinoputira rakasanganiswa neRN rinodzivirira yero kana raiswa pachiedza cheUV uye/kana kupisa. RN inoratidza simba rakanaka rekubatanidza muPVC ine plasticizer yakawanda, SBR ine mafuta akawanda, dehwe repamusoro, sirika nezvimwewo. RN inogona kusanganiswa nepolyester polyol nezvimwe zvinhu zvine hydroxyl kuti igadzire varnish yepolyurethane ine zvikamu zviviri kana pendi yemavara. Ine hunhu hwekuomesa nekukurumidza uye kudzivirira yero. Hunhu hwayo hwekutanga hwekugadzirisa nekukurumidza uye kupwanya ndiro zvakanakira zvayo zvikuru zvehuni.

Ruzivo rwekushandisa

RN iglue rine zvikamu zviviri. Mushure mekuwedzera chikamu chakati cheRN kune gundi, gundi rine zvikamu zviviri rakagadzirira kushandiswa rinofanira kushandiswa mukati menguva (hupenyu hwehari) iyo inotsanangurwa kwete chete nehuwandu hwayo hwerabha, asiwo nezvimwe zvinoshandiswa mukugadzirwa kwayo (semuenzaniso maresini, ma antioxidants, zvinonyungudutsa, nezvimwewo). Kana gundi rikasashandiswa mukati menguva iyi, rinogona kuwedzera kuoma kuisa uye viscosity yaro inowedzera nekukurumidza kusvika nguva isingadzoreki yegel yasvika. Saka, harichashandiswi.

Chipimo Chinokurudzirwa:

Kugadzira namatidza yezvikamu zana nehuremu (pbw) zvichibva pane:

Rabha yeGraft-Chloroprene(zvakawanda zverabha zvinenge 16%)	3-5% pbw RN
Rabha yechloroprene(zvakawanda zverabha zvinenge 20%)	5-7% pbw RN
Hydroxyl polyurethane(huwandu hwepolyurethane hunosvika 15%)	3-5% pbw RN

Kurongedza & Kuchengeta

Kurongedza:

Rudzi 1. 800g/bhodhoro, mabhodhoro makumi maviri mubhokisi rimwe, mabhokisi makumi maviri nemana kana makumi matatu mupallet rimwe;

Rudzi rwechipiri. 20kg/dhiramu, madhiramu gumi nemasere kana madhiramu makumi maviri nemanomwe mupareti imwe chete;

Rudzi rwechitatu. 55kg/dhiramu, madhiramu masere kana gumi nemaviri mupareti imwe chete;

Rudzi rwechina. 180kg/dhiramu, madhiramu mana mupareti imwe chete

Kuchengetera:

Ndapota chengetai mubhodhoro rekutanga rakavharwa 5℃-32℃, zvigadzirwa zvinogona kuchengetedzwa zvakagadzikana kwezvimedu gumi nezviviri.

Zvigadzirwa zvedu zvese zvinonzwa hunyoro zvakanyanya; Zvinogadzira carbon dioxide uye urea isinganyunguduke mumvura. Kana zvikasangana nemhepo kana/nechiedza, zvinokurumidzisa kuchinja kwemavara ezvigadzirwa.

(Asi basa rekushandisa richakanganiswa nebot.)

Kuchengetedzeka:

Hunhu hune njodzi, hunobatidza zvakanyanya, hunomutsa maziso, kana hukafemerwa hunogona kukonzera allergies. Kubatwa kakawanda kunogona kukonzera kuoma kweganda kana kupenga. Kunhuhwirira kwezvinhu kunogona kuita kuti munhu aneta uye anzwe vertigo.
