恒溫(wen)持(chi)粘(zhan)性測(ce)試儀專用于(yu)高(gao)溫(wen)環(huan)境(jing)下(xia)的膠(jiao)粘(zhan)帶(dai)持(chi)粘(zhan)性試驗(yan)，模擬膠(jiao)粘(zhan)帶(dai)在高(gao)溫(wen)環(huan)境(jing)中(zhong)，在規定的荷(he)重(zhong)下(xia)自動(dong)計時(shi)膠(jiao)帶(dai)所能保持(chi)的時(shi)間，以確認(ren)膠(jiao)帶(dai)粘(zhan)著的時(shi)效，當膠(jiao)帶(dai)自鋼(gang)板掉落后，計時(shi)器自動(dong)保留試驗(yan)時(shi)間，用來評定高(gao)溫(wen)環(huan)境(jing)中(zhong)膠(jiao)帶(dai)粘(zhan)著的持(chi)久性。

持粘(zhan)(zhan)性(xing)測(ce)試(shi)儀(yi)按照GB4852之(zhi)規定(ding)設計制造(zao)，適用(yong)于各種膠(jiao)(jiao)粘(zhan)(zhan)類制品的初粘(zhan)(zhan)性(xing)測(ce)試(shi)，如壓(ya)敏(min)膠(jiao)(jiao)帶(dai)、不(bu)干(gan)膠(jiao)(jiao)標簽、保護膜等(deng)。采(cai)用(yong)斜面(mian)滾球法，通過(guo)鋼(gang)(gang)球和試(shi)樣粘(zhan)(zhan)性(xing)面(mian)之(zhi)間以(yi)微(wei)小壓(ya)力發生短(duan)暫接觸(chu)時，膠(jiao)(jiao)粘(zhan)(zhan)帶(dai)對鋼(gang)(gang)球的粘(zhan)(zhan)附作(zuo)用(yong)來測(ce)試(shi)試(shi)樣初粘(zhan)(zhan)性(xing)。主要(yao)由傾(qing)斜板、放球器、支架、可調水(shui)平底座及鋼(gang)(gang)球等(deng)構(gou)成。

初(chu)/持粘(zhan)(zhan)(zhan)(zhan)性測(ce)試(shi)儀按(an)照GB4852之規定設計制(zhi)造(zao)，適用于各種膠(jiao)粘(zhan)(zhan)(zhan)(zhan)類(lei)制(zhi)品的初(chu)粘(zhan)(zhan)(zhan)(zhan)性測(ce)試(shi)，如壓敏膠(jiao)帶、不(bu)干膠(jiao)標簽、保(bao)護膜等(deng)。采用斜面(mian)滾球(qiu)(qiu)法，通過鋼(gang)(gang)球(qiu)(qiu)和試(shi)樣粘(zhan)(zhan)(zhan)(zhan)性面(mian)之間以微(wei)小壓力發生短暫接(jie)觸(chu)時，膠(jiao)粘(zhan)(zhan)(zhan)(zhan)帶對鋼(gang)(gang)球(qiu)(qiu)的粘(zhan)(zhan)(zhan)(zhan)附(fu)作用來測(ce)試(shi)試(shi)樣初(chu)粘(zhan)(zhan)(zhan)(zhan)性。主要由傾斜板、放(fang)球(qiu)(qiu)器、支架、可調水平底座及鋼(gang)(gang)球(qiu)(qiu)等(deng)構(gou)成。
