PTFE hian non-stick property a neih hi khandaih hriam pahnih nei a ni. PTFE hi release application atan a tha hle a, mahse engmah a bond lo tihna a ni bawk – a chunglam chu treat hmasak a nih loh chuan.

atan hian hmanraw lian pahnih a awm a PTFE surface treatment : high-temperature melting method leh sodium-naphthalene etching method . An thatna, tihkhawtlai, leh boruak tichhe thei chi hrang hrang an nei vek a ni.

Aokai PTFE chuan bonding application atan hian method pahnih hi a evaluate tawh a ni. He thuziak hian an hlauhawmna, interfacial performance (bond strength, weather resistance, effective window), leh application recommendation te a khaikhin a ni.

Core Difference chu a hmasa berah a awm

Bawlhhlawh tuiah hian naphthalene, sodium metal, leh tetrahydrofuran (THF) te a awm a – chung zawng zawng chu hlauhawm anga ngaih a ni. Kum sawm kalta chhung khan regulated region-ah chuan disposal cost hi 300-500% zetin a pung a ni. Dawr tenau thenkhat chuan etchant hi hman nawn leh an tum a, mahse batch khat hnuah a activity chu 50% zetin a tlahniam thung. High-temperature melting method hian harsatna awm mahse, a bul berah chuan boruak atanga hlauhawm (toxic fumes) a siam a, chu chu fume hood dik tak leh thermal oxidizer hmanga man theih a ni. Mahse, energy senso hi a tam hle – melting PTFE hian 327°C aia sang temperature a mamawh a, thermal decomposition control nan inert atmosphere emaw vacuum emaw a mamawh bawk.
