Fluoroelastomer hi kum 1950 chho lai vel khan kum 60 chuang zet chu DuPont chuan hlawhtling takin an siam chhuak a, industrial production-ah an dah lut tawh a ni. Oil resistance tha tak, temperature sang tak resistance, concentrated acid resistance, alkali resistance, radiation resistance, corrosion resistance, oxidant resistance chak tak, chemical resistance tha tak, gas tightness tha tak, physical leh mechanical property tha tak, leh electrical insulation, compression hniam leh permanent deformation a nei bawk. Synthetic rubber bik a nih angin chemical industry, aerospace, automobile, petroleum industry, machinery, electronics leh thil dang dangah te hman a ni nasa hle. Fluorine rubber hian performance tha tak a nei a, hman theihna zau tak a nei bawk. China-in independent taka siam, low-temperature fluoroether rubber hi Long March series-a launch vehicle servo mechanism seal siamnaah hlawhtling takin hman a ni tawh a, fighter jet-ah te, oil pipe-a tank thar siamnaah te, electrical circuit sheathing leh accessories dangteah te pawh hman a ni tawh bawk. Civil use for automotive parts, nitin pung zel, industrial field-ah zawi zawiin fluorine rubber hmanna tipung.

Fluorine rubber hian a chunga kan sawi tawh ang khan media leh temperature sang tak laka invenna tha tak nei mahse, fluorine rubber product siam leh siam chhuahna kawngah hian thil danglam leh harsatna engemaw zat a awm a, chung zingah chuan a tlangpuiin a mixing laiin scorched dead material, open refining sticky rollers, a chang chuan film chhuah hnua cut leh check-naah dots dum te te hmuh tur a awm a, product te hi a awlsam hle tear, shrink and crack, edges burn, joint-ah traces awm, rubber awm lohna, product deformation, serious mold staining leh thil dang, product quality tichhe thei. Thil siam quality a nghawng nasa hle.

A chunga kan sawi tak thil siam chhuah danah thil dik lo awmte chhanna atan a hnuaia solution te hi siam a ni.

Point 1. Fluorine rubber hmanga thil thi mixed

A chhan chu ingredient rubber hian sulfur yellow emaw sulfur yellow products nen a inzawm a, enterprise tam tak chuan refining fluorine rubber machine bik an nei lo va, sulfur yellow rubber material dang refining fo thin, tihfai a awm lo, emaw ingredients sulfur yellow emaw tui emaw avanga accident-a tihbawlhhlawh, chuvangin chu chu scorching avanga fluorine rubber promoter nen inzawm theih a ni a, a nih loh leh fluorine rubber chunglam activation decomposition siamna atana tui chanvo. Solution, special machine tha ber, a nih loh chuan, refining hmaa fluorine rubber conversion-ah pawh a awm tur a ni a, baffle plate leh material plate chu a thianghlim vek tur a ni a, tui leh sulfur yellow nena inzawmna chu pumpelh vek tur a ni, ingredients application special tools, a material a spoon, cross-contamination ven nan. Calcium hydroxide leh magnesium oxide te chu sealed-in dah la, hman theih turin dah rawh.

Point 2. A sticky roller thil thleng

A bik takin opening machine-a mixing process-ah chuan rubber material chu back roller-ah nghet takin a inkhuh a, a nih loh leh a rualin rollers pahnih hma leh hnuah a inkhuh a, chu chuan rubber material hlui chu refining a turn thei lo va, a hnuhnung zawk chu agent dah belh nen awlsam takin flakes-ah press a, a tla thla a, chu chuan uneven dispersion a thlen a ni. Roller-a fluorine rubber material a innghat chhan ber chu fluorine rubber-a Menny tlem emaw molecular content hniam emaw vang a ni. He harsatna chinfel dan tur chu raw rubber viscosity 70 vel thlan a ni a, raw rubber molecular weight distribution tawi tak hmang a, chutah chuan Brazilian wax emaw fluorine wax emaw low molecular weight polyethylene emaw tlem te te chu formula-ah dah a ni a, chu chuan sticky roller phenomenon pawh a chinfel thei bawk.

Point 3. Compounding rubber chhunga hmun dum te te chungchang

A chhan chu fluorine rubber compounding agent powder thenkhat dispersion vang a ni a, a nih loh leh powder moisture caking vang a ni a, chu chu acid absorbers calcium hydroxide, magnesium oxide leh diatomaceous earth, barium sulfate, etc., solution, compounding agent moisture ven nan leh thin pass process tichak turin a ni.

Point 4. A product hi a hrual awlsam hle

A chhan chu, burr thick lutuk, tearing laiin trimming, emaw mold with too tight, out of the mold burr parts te chu mold ah a tang thei a, product atanga awlsam leh tearing hmain burr, uneven force tearing starting, uneven force tear the product. A châng chuan mold cavity processing chu a rough a, a nih loh leh adhesive material chu mold-ah a innghat a, vulcanization a zawh chuan mold chu lak chhuah harsatna a siam a, awlsam takin product chu a ti chhe thei bawk. Tin, vulcanization temperature a sang lutuk a, hei hian thil siamte chu a ti chhe thei a, a tikehsawm awlsam phah bawk ang. A chunga kan sawi tak abnormality atan hian a hnuaia lam atang hian chinfel theih a ni: mold processing precision chu cavity roughness Ra 0.8 aia tlem a ni tur a ni a, fit gap chu a lian lutuk tur a ni lo, vulcanization temperature control 170 degree inkar a awm chu a tha tur a ni a, rubber material weighing pawh a dik tur a ni.

Point 5. Shrinkage leh cracking chungchanga harsatna

Chu chu mold hawn a nih chuan pressure lakchhuah a nih vang a ni a, fluorine rubber a tlahniam a, burr part chu mold chhungah a innghat a, chuvangin product part leh burr inkarah tensile force a siam a, chutiang chuan product leh burr chu a inthen a, crack enclosure chu product part-ah a zau chuan shrinkage leh cracking phenomenon a thlen thin. A solution chu vulcanization temperature dik taka tihhniam a, Menny viscosity chu 70 [ML1+4] 121 degree vel a thlan a ni a, chutih laiin mold fit degree chu a dik tur a ni a, a loose lutuk lo va, a tight lutuk tur a ni lo.

Point 6. Edge chu kang ang a ni

A vulcanization temperature a sang lutuk a, a bik takin thick products, a remchan dan angin vulcanization temperature tihhniam theih a ni.

Point 7. Joint-ah hian trace a awm

I t chu adhesive material lap part chu a fused vek loh vang a ni a, emaw, adhesive strip-ah bawlhhlawh emaw oil fouling emaw a awm avangin a solution chu preformed adhesive strip chu storage, transportation, loading glue-a thianghlim taka dah a ni a, pollution ven nan.

Point 8. Glue awm lohna

Mould structure leh glue liquidity nen a inzawm a ni. Closed mold hian open mold aiin glue tlakchhamna a siam tam zawk. A solution chu rubber liquidity siamrem a, mold cavity chhunga air venting hole hawn hi a ni.

Point 9. Thil siam chhuah tihdanglam

A chhan chu fluorine rubber shrinkage rate a lian vang a ni a, product shrinkage anisotropy molding hnuah, rubber thermal expansion coefficient chu kawng hrang hrangah a danglam a, vulcanization process pahnih chuan cross-linking dang a siam ang, a bik takin sulfur hnuaia vulcanization section pakhat, product vulcanization pahnih, deformation langsar zawk, chutiang chuan full-linking in a period of vulcanization time, product deformation vulcanization pahnih awm loh nan.

Point 10.Mold stain na tak a ni

Kan hmang tlangpuiin 26 type fluorine rubber, phenol vulcanization system, vulcanization process-ah hian HF siam chhuah a ni ang a, acid chak tak a ni a, mold-ah corrosive effect nasa tak a nei a, acid absorbent dahna tur formula chu HF siam chhuah chu absorb a ni a, mold-a bawlhhlawh a awm loh nan. Solution chu formula ang zela calcium hydroxide leh magnesium oxide tling hman a ni a, a dosage chu a tlangpuiin part 6 leh part 3 a ni a, Brazilian wax chu formula-ah hian dah theih a ni a, chu chu vulcanization neih laiin rubber surface-ah migrate in film a siam thei a, chu chuan mold chu a bawlhhlawh loh nan a siam thei a ni.

A chunga fluorine rubber siam leh siamna lama thil dik lo awm fo sawmte hi kawng hrang hrang hmangin chinfel theih a ni.
