Step 1: Raw Material buatsaih - Foam tha tak, a bulpui ber raw materials te hi a pawimawh ber a ni
Silicone material: Hei hi foam "base" (liquid silicone form-a tarlan) atan a thawk a, room temperature-ah fluidity chu component dang nena inzawm tlat turin a vawng reng a ni. Purity level hian foam-a thermal stability (-60℃to 200℃temperature tolerance) leh elasticity chu direct-in a tichiang a ni. Premium liquid silicone hian compression tih nawn leh hnuah pawh rang taka rebound a pe thei a, hun rei tak chhunga hman tawh chu a tar emaw, a tihkhauh loh emaw a veng thei a ni.
Fume silica (fume-bonded silica): Foam tan "structural reinforcement agent" tih a ni. He powder dum tha tak hi liquid silicone nen a inbel chuan "microscopic framework" angin a thawk a, chu chuan structure chu a thlawp a, foam-a tear resistance leh strength-- chu nasa takin a tichak a ni. Chutiang a nih loh chuan foamed silicone chu a nem leh a fragile a, hman laiin real-world compression leh friction a tuar thei lo ang.
Dik tak chuan, application scenario a zirin auxiliary component tlemte (expansion power pe thei tur foaming agent leh curing tihhmasawn nan vulcanizing agent ang chi) te dah belh a ni ang a, mahse liquid silicone leh fumed silica te hi foam performance tichiangtu "core CP" an ni fo thin.
Step 2: Mix leh stir -- A chhunga thil awmte chu "Get close"-ah dah rawh.
A thil telte chu an siam fel tawh chuan special mixing device-ah an lut a, "team up" turin. Liquid silicone a fluidity hian mixing a ti awlsam zawk a, mahse key point pahnih a awm a, chungte chu:
Temperature Control: 50℃hnuaiah dah tur a ni , chutiang a nih loh chuan a hnuaia foaming hian "lose control" a ti hmasa ang;
Mixing time: A tlangpuiin 20- minute 30, gas phase silica a darh vek hma loh chuan, rubber compound chuan uniform leh delicate state a rawn present a -- cream blend tha tak ang maiin, granular sense nei lovin, foaming hnua boruak hole inang tlang tak a awm theih nan.
Mixing chu uniform a nih loh chuan eng nge thleng ang? Hmun thenkhatah chuan gas phase silica clusters leh foam te chu a harsa dawn a; Hmun dangah chuan a content a tling tawk lo va, foam pawh a nem lutuk ang a, a chhe awlsam ang. Chuvangin, he step hi "uniform foaming" bulpui ber a ni.
Step 3: Foam Molding -- Foam-a "Transformation Moment" tih hi a dik lo a ni.
Hei hi step mak ber a ni! Mixed compound chu "foaming workshop" ah thawn a ni a, a kalphung hmangin a inthlak danglam a ni:
Continuous foaming process: "rolls/plates" mass production hmasa ber, pre-treated rubber compounds te chu precision-specialized equipment hmangin uniformly thick sheet-ah an press a. He step hian final product flatness ensure na tur lungphum a siam a ni. Chumi hnuah chuan sheet te chu conveyor belt-ah awlsam takin an phurh a, multi-meter-long high-temperature curing chamber---a core area chu foaming leh solidification atan an dah a. Chamber chhungah chuan, rubber sheets te chu conveyor belt-ah an kal zel a, chu chuan lumna nasa tak hnuaiah foaming reaction an nei a: chu material chuan zawi zawiin cell tha tak tak, uniform tak tak, expanded volume nei a siam a, chutih rual chuan thermal curing an nei a, chu chuan elasticity leh structural stability a ti sang a ni.
Material chu oven atanga a chhuah chuan foam roll a lo ni ta a, a texture leh flat shape (a nih loh leh a tul angin sheet-ah cut) a ni.
Key: Engtin nge pores hi control a nih? I ngaihtuah mai thei: Engvangin nge foam bubble thenkhatah hian sesame (0.1-0.5mm) ang chi hole leh mung beans (1-3mm) ang chi hole an neih?
• A bulpui ber chu foaming agent leh heating speed a\\anga teh a ni: foaming agent tam poh leh a heating a chak chuan air hole a lian zawk (shock absorption leh sound insulation atan a tha) Chutiang a nih loh chuan air hole chu a tha (waterproof sealing atan a tha).
• Pores of high quality foam chu a inang tlang vek tur a ni -- magnifying glass hmanga en a nih chuan a lian zawng chu a bul berah chuan a inang vek a, "hole lian tak tak chungah hole lian tak tak" tih pawh a buaithlak dawn lo a, chu chu a kalphung a ni.
Step 4: Post-Processing -- "Tisa lam enfiahna leh siamthat dan tur chipchiar tak" tih chu foam tan a ni.
Foam mai mai foam chu direct-a hman theih a ni lo. It needs to undergo "Fine grinding" : Secondary Vulcanization: Oven-ah 200℃vel a 2- darkar 4 chhung dah la, a la awm volatile substances te chu paih chhuak la, a hnu lama hman a nih chuan "oiling" emaw shrinkage emaw tih loh nan. Cutting/Trimming: Roll materials chu standard sheet-ah an tan a, a hmun dik lo kilte chu dimension dik tak siam turin an ground a (entir nan, waterproof foam tan chuan error chu 0.1mm aia tam lo tur a ni a, chuti lo chuan a leak thei bawk). Performance spot-check: density (0.3 atanga 0.8g/cm3 inkar, a tul anga siamrem) leh compression rebound rate (service life tihfel nan) tehna.
Tichuan , silicone foam sheet chu a zo ta .
