Ko ngā hua huaora katoa he mea ahu mai i te penupenu miro tūturu, i te penupenu rakau rānei, e hangaia ana mā te whakaetere. He rerekē ngā kaihoko whakaetere e whakamahia ana e ngā hua cellulose rerekē. Ko te kaihoko whakaetere e whakamahia ana i roto i te hydroxyethyl cellulose (HEC) ko te ethylene oxide, ā, ko te kaihoko whakaetere e whakamahia ana i roto i te hydroxypropyl methylcellulose (HPMC) ko ētahi atu momo kaihoko whakaetere (chloromethane me te propylene oxide).
I roto i te peita szone tūturu me te peita latex, ka taea te whakamahi i te hydroxyethyl cellulose hei whakamātotoru.
He ngāwari te whakapūpū i te peita kōhatu tūturu nā te nui o te kōhatu me te kaha o te matū. Me tāpiri he whakamātotoru hei whakanui ake i tōna matotoru, kia tutuki ai te matotoru e hiahiatia ana mō te rehu i te wā hanga, kia pai ake ai te pumau o te rokiroki, kia tutuki ai hoki he kaha.
Ki te hiahia koe kia pai te kaha o te peita kōhatu tūturu, kia pai te ātete ki te wai, kia pai hoki te ātete ki te huarere, he mea tino nui te whiriwhiri i ngā rauemi mata me te hoahoa o te tauira.
I raro i ngā āhuatanga noa, ka nui rawa te nui o te wai whakapūkara e whakamahia ana i roto i te peita kōhatu tūturu kounga teitei.
Hei tauira, i roto i te tāne peita kōhatu tūturu, tera pea he 300kg o te emulsion kiriaku parakore me te 650kg o te onepu kōhatu tae tūturu. Ina he 50% te ihirangi totoka o te emulsion, ko te rōrahi o te 300kg o te emulsion i muri i te whakamaroke he tata ki te 150 rita, ā, ko te rōrahi o te 650kg o te onepu he tata ki te 228 rita. Arā, ko te PVC (kukū rōrahi tae) o te peita kōhatu tūturu he 60% i tēnei wā, nā te mea he nui, he koretake hoki te āhua o ngā matūriki o te onepu tae, ā, i raro i te āhua o tētahi tohatoha rahi matūriki, tera pea kei roto i te CPVC (kukū papatipu whakahirahira) te peita kōhatu tūturu kua maroke. (Kukū rōrahi tae) tata. Mō te whakamātotoru, ki te whiriwhiri koe i te cellulose me te matotoru tika, ka taea e te peita kōhatu tūturu te hanga i tētahi kiriata peita tino oti me te matotoru hei whakatutuki i ngā whakaritenga mahi matua e toru o te peita kōhatu tūturu. Mena he iti te ihirangi o te emulsion peita kohatu tūturu, ka tūtohutia kia whakamahia te cellulose he matotoru ake hei whakamātotoru (pērā i te matotoru 100,000), inā koa i muri i te pikinga o te utu o te cellulose, ka taea te whakaiti i te nui o te cellulose e whakamahia ana, ā, ka pai ake te mahi a te kohatu tūturu.
Ko ētahi kaihanga peita kōhatu tūturu he iti te utu, ā, e whakamahi ana i te hydroxypropyl methylcellulose hei utu mō te hydroxyethyl cellulose, nā te utu me ētahi atu āhuatanga anō hoki.
Ki te whakatauritea ki ngā momo cellulose e rua, he pai ake te pupuri wai o te hydroxyethyl cellulose, kāore e ngaro te pupuri wai nā te gelatin i te pāmahana teitei, ā, he ātete ki te harore. Hei whakaaro ki te mahi, e taunakihia ana kia whakamahia te hydroxyethyl cellulose me te matotoru o te 100,000 hei whakamātotoru mō te peita kōhatu tūturu.
